I can extract side effects

"These purchased finished materials are not good. The test results show that the strength and toughness are not up to our requirements."

Wang Dali picked up several small black cylindrical tubes on the table, played with them for a while, and said with a frown.

The engineer next to him said with a wry smile.

"Boss, the only common giant magnetostrictive material on the market is Terfenol-D. This material has been available for decades, and the manufacturing process is very mature. It can also be produced in China."

"Manufacturers can supply rings, round tubes, round rods, and various finished products of powder, and the price is not expensive. They can also provide processing such as slotting and lamination to reduce losses."

"This is actually enough for ultrasonic transducers."

"You know, Johnson \u0026 Johnson's ultrasonic scalpel uses piezoelectric ceramics. We can use magnetostrictive material rods, which are already more advanced than Johnson \u0026 Johnson's products."

Wang Dali shook his head: "But its own strength is not high, it is very brittle, and it cannot be further processed. At the same time, it cannot maintain high-intensity work under high power."

"Otherwise, let's look at other functional materials."

The engineer said with a bitter face: "We have tried Galfenol (iron-gallium alloy), iron-cobalt-vanadium alloy and some iron-nickel alloys, but we couldn't find a better material."

He asked cautiously: "How about we consider piezoelectric ceramics?"

Wang Dali shook his head even more: "No, Johnson \u0026 Johnson, Medtronic uses piezoelectric ceramics as transducers."

"These guys are all masters of ultrasonic scalpel, especially Johnson \u0026 Johnson. The first ultrasonic scalpel was made by them. It is the ancestor of ultrasonic scalpel. It has been decades now. Piezoelectric ceramics can still be played. What kind of trick?"

"Believe it or not, just the patent pool, people will fill up all the pits, and you can't get around it at all."

"You follow other people's buttocks, and you can only step on the footprints left by them. How can you fight with them?"

"So, we can only change our R\u0026D thinking and use a magnetostrictive ultrasonic knife."

The engineer rubbed his forehead and said worriedly: "These are the ready-made civilian materials, and the choices are very limited. Is it possible to let the manufacturers improve the research and development materials themselves? That is too difficult. I don't think they have the strength."

Wang Dali chuckled and said, "We don't need them to research and develop, we have ready-made material formulas ourselves."

The engineer was overjoyed immediately: "Great, let's ask them to order it directly."

Wang Dali asked back: "Do you think that with the level of these manufacturers, a brand new rare earth alloy can be produced according to the formula?"

"This..." The engineer was speechless for a moment. He also knew that the level of these rare earth materials private enterprises could only provide ready-made materials or finished products. To produce new giant magnetostrictive materials, the process alone had to be eliminated. More than half.

Wang Dali thought of the rare earth alloy material in the Ultrasonic Knife file, and couldn't help but feel a headache.

The complicated formula and manufacturing process inside made him dizzy just by looking at it.

"It seems that we can only ask the national team for help."

"Professional matters should be left to the experts."

*****

Huaxia Iron and Steel Research Institute, a subsidiary of the Functional Materials Research Institute.

As a research and development base for new materials in the Huaxia metallurgical industry, it has developed and produced a large number of key materials for key projects such as launch vehicles and manned spacecraft. It is an international top research and development center in the field of materials.

Feng Qihang is the vice president in charge of scientific research. Not long after he arrived at the office that day, he had just had a drink of water when he heard someone knocking on the door.

"Come in!"

The one who entered was a researcher, holding a piece of paper in his hand, with a look of shock and joy on his face.

"Feng Yuan, we have received a request for technical cooperation from a company. They want to produce a giant magnetostrictive material for use as an ultrasonic transducer. Can we provide a batch of samples first?"

"Oh?" Feng Qihang raised his head curiously, and asked, "Which alloy company is it? Saturn Rare Earth? Or Huaxia Rare Earth?"

The researcher shook his head: "No, it's the Sanqing Group."

Feng Qihang was taken aback immediately: "It's the pharmaceutical group Sanqing? Aren't they a pharmaceutical company? How can they research rare earth alloys?"

The researcher explained: "Sanqing Group also makes medical devices. They recently developed an ultrasonic knife, and they want to use giant magnetostrictive materials on their own ultrasonic transducers."

Feng Qihang nodded: "I see, why don't they use existing products on the market? Can't Terfenol-D work?"

"It is said that it does not meet the requirements of their products, so they want to cooperate with us to produce a new material."

Feng Qihang couldn't help frowning: "Terfenol-D is already a very mature product with a wide range of uses. If it doesn't meet the requirements, their standards for new materials may be very high."

"I'm afraid this new material is not easy to develop."

The researcher interjected: "We are not looking for research and development, but production. They have already developed a new rare earth alloy. Because they have strict requirements on the production process, they asked us to cooperate."

"What?" Feng Qihang stood up from his chair in shock: "Can Sanqing develop new materials? Or super magnetostrictive materials?"

He couldn't wait to ask: "Is there any performance parameter? Show it to me."

"Yes." The researcher handed over the paper in his hand, on which the parameters of some new materials were simply written.

Feng Qihang grabbed it and immediately glanced at it.

Magnetostriction coefficient: ≥10000PPM

Tensile strength: ≥250Mpa

Compressive strength: ≥2600Mpa

Curie temperature: 1080°C

Density: 7.05g/cm3

Energy density: 140~250KJ/m3

Response speed: \u003c0.1μs

"This..." Feng Qihang's eyes widened, as if seeing a ghost, he shook his head again and again: "This is impossible."

"This performance is at least ten times stronger than Terfenol-D. It is impossible to have this kind of alloy material."

There was a "snap".

He slapped the paper on the table and stared at the researcher opposite, with a hint of anger on his face.

"Are you sure this is true? Didn't you receive a scam call?"

The researcher was taken aback, and hurriedly waved his hands and said, "No, no, it's really Sanqing Group's call. It seems to be a technical person in charge of equipment, called Wang Dali. The information came over for an interview."

Feng Qihang immediately turned his anger into joy: "Since you want to come here in person, then you shouldn't be a liar."

"But the performance of this writing is too exaggerated, how can it be realized?"

"Could it be that he bought the technology from somewhere, was deceived, and then wanted to find us to make it out of his whims."

His heart suddenly sank, and he felt that this situation was not impossible.

So he pondered for a moment, and ordered: "Well, you agree to come down first, and after he comes, see the technical information, and then discuss it together to see if it is feasible."

"Remember, you can't talk too much, and you can't promise anything before seeing the information, lest they have unrealistic fantasies."

A few days later, Feng Qihang welcomed Wang Dali and his party in the office.

Both parties sat down in the conference room.

Before Feng Qihang could speak, Wang Dali handed over a document with a smile.

"I'm sorry, because this involves our company's top-secret technology, please sign a non-disclosure agreement."

Seeing the other party's serious face, Feng Qihang couldn't help but want to laugh.

He also had a straight face, nodded and said: "Since your company takes this new material so seriously, then I will listen to you."

At his suggestion, several participants from the Institute of Functional Materials signed a non-disclosure agreement.

Only then did Wang Dali heaved a sigh of relief, and said with a smile, "Thank you very much, let's get to the point."

He took out his computer, connected to Sanqing's remote network through the key, and displayed a prepared ppt in front of everyone.

"This?" Feng Qihang read a few pages, and instantly lost his composure.

Especially after seeing the alloy ratio and analysis, he was completely stunned.

"It turned out to be true! Such a powerful giant magnetostrictive material actually exists!"

"My God, this is a great discovery that shocked the world!" He trembled with excitement.

Several other technicians in the research institute stared blankly at the ppt, unable to utter a word.

Wang vigorously explained the PPT, completely oblivious to the strangeness of the others.

There is a lot of professional knowledge involved in it, and he doesn't know why, so he speaks a little hard and skips a lot of technical content.

After finally finishing his speech, he showed an awkward yet polite smile, rubbed his hands together and said, "That's about it."

"Dean Feng," he looked at Feng Qihang full of expectation, "What do you think of this material? Is it difficult to produce it in the laboratory?"

Feng Qihang looked at the screen with a fascinated expression, as if he didn't hear him.

"Dean Feng? Dean Feng?" Wang Dali called out a few times in a low voice.

Only then did Feng Qihang come to his senses as if he had just woken up from a dream.

"Papa papa!"

He immediately stood up and applauded excitedly.

"Mr. Wang, you Sanqing really came up with something incredible."

"This is a breakthrough achievement. Since Terfenol-D was developed in Eagle Country's Naval Laboratory, the world has been developing giant magnetostrictive materials, but in recent years, research and development has stagnated."

"Although the industrial application is very extensive and the prospect is promising, there has been no major breakthrough in the most cutting-edge research."

"Until now, Sanqing Group has quietly made such a major breakthrough. It is so surprising. It is definitely the biggest achievement in our materials industry in recent years!"

"With it, our country will usher in new developments in aerospace, national defense, industry, medical care and other major fields, which is really gratifying."

"Come on, everyone applaud with me, and express warm congratulations and sincere thanks to the comrades of Sanqing!"

Everyone else stood up immediately and applauded enthusiastically.

Looking at the scene in front of him, Wang Dali was shocked.

"No, Dean Feng, you are, don't, don't, don't, we absolutely dare not be that."

After finally pushing the other party down on the seat, seeing everyone's excited expressions, Wang Dali also showed a sympathetic smile.

He remembered the scene when he just saw the Ultrasound Knife material, and he was so pleasantly surprised and excited.

However, Feng Qihang's next words froze his smile on his face instantly.

"I'm sorry, your new material is too powerful, and it is very likely that it is classified. I have to report to my superiors."

*****

Kunming, Sanqing Headquarters.

"Buzzing~" The phone on the table rang.

Wei Kang picked up the phone and looked at it, and immediately connected the call.

"Old Wang, hello, why are you free to call me today?"

It was Wang Guiqing who was on the other end of the phone, and said with a smile, "Mr. Wei, you are a busy person. How dare I bother you."

"But I didn't expect that you Sanqing would make such a big deal when you first started making medical devices."

Wei Kang asked at a loss: "What's going on? Recently, several medical devices have been developed, but nothing surprising."

He thought to himself, among these new projects, the artificial heart is more gimmick and attracts people's attention, but it's not enough for the superior to make a special call.

Wang Guiqing laughed and said, "Oh, Mr. Wei's tone is not surprising, such an understatement, he is indeed the king of medicine in China."

Someone next to him seemed to chuckle and whispered a few words.

Wang Guiqing continued: "Mr. Wei, I heard that Sanqing has developed an ultrasonic knife, and the transducer inside uses a giant magnetostrictive material? Did you develop this material yourself?"

Wei Kang's heart moved, and he said casually: "Yes, as expected of Mr. Wang, the news is well-informed."

Although he took a lot of high technology from the system, he didn't understand all the technical details in it, and basically handed it over to his subordinates for research and development.

Hearing this at this time, I immediately understood that it must be the transducer material that attracted the other party's strong attention.

"It's not that I'm well-informed, but Huaxia Iron and Steel Research Institute told me that they said that Sanqing Group came to the door to cooperate in the production of a new material. They have made a huge breakthrough in giant magnetostrictive materials, which can be used in Aerospace, and the Navy's sonar system, so report up."

Wang Guiqing said with a smile: "No, the superior sent me to ask."

Wei Kang secretly breathed a sigh of relief, and said with a smile: "This is indeed the case, as you know, for the research and manufacture of rare earth alloys, the General Iron and Steel Research Institute is the national team with the strongest strength, and we can't produce it ourselves, so we can only find them. Cooperation."

"But this material, my original purpose was just to make a transducer for Sanqing's ultrasonic scalpel, and I had no other ideas."

"You also know that foreign companies in medical equipment are relatively strong. If we want to grab meat from a group of wolves, we will naturally work hard to develop new technologies."

"Mr. Wei, are you trying too hard to grab meat?"

A thick man's voice suddenly said with a smile.

Before Wei Kang could react, Wang Guiqing quickly explained: "Mr. Wei, the people from the Navy rushed over immediately when they heard about this. They are right next to me now. How about we talk together?"

"People from the navy?" Wei Kang was a little surprised.

The thick voice with a bit of vicissitudes continued: "Mr. Wei, hello, please allow me to introduce myself. I am Ouyang Du from the Naval Equipment Research Institute. It is a pleasure to meet you. I have heard that Sanqing Technology is very strong in the past. , Only today did I truly see how strong it is.”

His voice was full of admiration: "You three Qings are really powerful. You just made such a big commotion just by studying an ultrasonic knife."

"Let me ask, have you applied for a patent for this giant magnetostrictive material?"

Wei Kang nodded: "That's natural, but the Patent Office just told me this morning that this patent will be converted into a confidential patent."

"Then it seems that the Patent Office has done its job well." Ouyang Du said with a smile: "Giant magnetostrictive materials are national strategic functional materials, which are of great significance and have immeasurable development prospects in the field of national defense."

"Whether it is the invention or early application of this material, it is directly related to the military industry, especially the navy."

"In fact, the first giant magnetostrictive material, that is, Terfenol-D, was born in the Eagle State Naval Weapons Laboratory. It was applied in an early stage and became a strategic material prohibited from export."

"We now have a very urgent need for related materials, especially in the development of sonar systems and ultrasonic weapons."

"The advent of your new material is like sending pillows to us when we are sleepy. Thank you so much."

"Mr. Wei, in addition to the ultrasonic knife, Sanqing might as well expand its business and support national defense construction? How about it?"

Wang Guiqing interrupted suddenly: "There's also aerospace, I guess Academician Xie will call you soon."

Wei Kang grinned: "As it should be, the development of Sanqing is inseparable from the support of the state. It is naturally desirable to be able to contribute to aerospace and national defense."

"It's just that the extent to which it can be supported depends on the output of the steel group."

"Hahaha~"

The three of them laughed tacitly at the same time.

The General Institute of Iron and Steel Research is the research center of Sinosteel Group. Basically all new aerospace and military materials are developed by them, including but not limited to the Shenzhou spacecraft and the Chang'e lunar probe.
