Qin Anguo left with a reply, and Academician Zhang Pingxiang stayed and prepared to participate in the optimization of high-temperature copper-carbon-silver composite superconducting materials at the Sichuan-Sea Materials Research Institute.

An academician and big shot who is also a founder in the superconducting materials field has made the institute much more active.

Some researchers who are more courageous and more ambitious in academics have begun to approach the question after knowing the identity of this boss.

For Zhang Pingxiang, he will always refuse any issues related to superconducting materials. This is a true scholar who is addicted to the field of superconducting materials and has a heart that will always climb up.

Of course, under normal circumstances, if there are researchers in the laboratory who ask Xu Chuan to communicate with questions, Xu Chuan will not refuse.

But most of the time, he was not in the lab.

Just as Fan Pengyue said, this is a hand-off manager. Whenever he remembers or needs it, he will come and leave after using it.

So most of the time the researchers in the laboratory wanted to ask Xu Chuan for questions, they couldn't find anyone.

Now there is a new boss, and if you don’t seize the opportunity, you will miss it and regret it.

Academician Zhang Pingxiang took the initiative to ask to stay and study and optimize the copper-carbon-silver composite material. Although Xu Chuan just wanted to see him as an ordinary researcher in the laboratory, how could Xu Chuan make such an arrangement?

For a big bull at the level of academician, the business trip costs can no longer be calculated with money.

Fortunately, Fan Pengyue has sufficient experience in dealing with such things. He followed Chen Zhengping during his doctorate, and he basically handled such things.

As for Xu Chuan, he didn't care about this.

After Academician Zhang Pingxiang came, he almost lived in the research institute. The two kept exchanging ideas and opinions in the laboratory, looking for a route to optimize the physical properties of high-temperature copper-carbon-silver composite superconducting materials.

"How about doping some zirconia through nanotechnology? Zirconia itself is a superconducting material at ultra-low temperatures. Its superconducting principle comes from torsional crystal structures. Theoretically, it should be very suitable for copper-carbon silver materials like you."

In the laboratory, Academician Zhang Pingxiang looked at the data on the computer screen, thought for a while, and spoke.

Xu Chuan thought for a while and said, "You can give it a try, but I don't feel that I hope it's too much. Unfortunately, the mechanism data of zirconia was not entered into the material model, so I can't simulate it through the model."

These days, he has been talking with Zhang Pingxiang about how to change the brittleness of copper-carbon-silver composite materials.

Compared with metals, brittleness and difficulty in deformation are a major feature of ceramics. In order to improve the brittleness of ceramics and improve their toughness, it is generally generally used to reduce the grain size and make them submicron or nanometers to improve plasticity and toughness.

Or use effective methods such as doped zirconia toughening, phase change toughening, fiber toughening or in-situ growth enhancement to improve it.

But these methods are OK when putting on other ceramic materials, but it is difficult to work on superconducting materials.

Because the superconducting mechanism of high-temperature superconducting materials itself comes from the strong correlation effect between electrons. If other materials are doped or grain size and structure are changed, it is very likely that superconductivity failure or reduction will be directly caused.

If the reduction is not large, it is still acceptable. But based on the current data, the reduction of this amplitude may be quite high.

Upon hearing this, Zhang Pingxiang asked with interest, "If your model is really to be perfected, it may completely subvert the research methods of the materials industry, but it is difficult to do it."

"And as the mechanism data of materials is added more and more, the size of the model will become larger and larger. The existing supercomputers may not be able to carry this model soon. Perhaps the quantum computer is its return."

In the past few days, at the Sichuan-Sea Materials Research Institute, he not only exchanged a lot of knowledge about superconducting materials with the person in front of him, but also saw the real "big killer".

Although the model in front of us can play a very limited role, it has opened up a completely new path in the field of materials research.

In the past research on materials, research on a new material was generally explored based on experience.

Although computer simulation can also play a certain auxiliary role in this process, such as using computer simulation technology to predict and analyze the properties and behavior of materials.

This link includes theoretical calculations, molecular dynamics simulations and finite element analysis, etc. But in fact, the simulation results are actually not very accurate, and the role played in the entire material research process is still quite limited.

The model within the Sichuan-Hai Materials Research Institute is different. It is derived from the root based on the mechanism of the material, and can directly simulate the entire synthesis process with the help of computers and models.

To be honest, when working on materials, I basically thought about doing this kind of thing, but no one can do it.

Because of insufficient mathematical skills, it is too difficult to establish a mathematical model for materials research based on the mechanism of materials.

Only the one in front of me has this ability and this mind.

Xu Chuan smiled and said, "I'll worry about this in the future. At least it can provide us with a lot of help at the moment."

After a pause, he continued, "As for the doping of zirconia, we can arrange for researchers to do an experiment and see how it works."

Zhang Pingxiang said, "I will do this experiment myself. To be honest, I am quite optimistic about it."

These days, he has communicated a lot with the young scholar in front of him. In addition to seeing his extensive knowledge of materials science, he also has some comparative ideas in his heart.

After all, when he reaches his level, he can be said to be standing at the top of the pyramid in the field of superconducting materials.

As the saying goes, there is no first in literature and no second in martial arts. He also wants to try to see whether he is stronger if he has been immersed in the field of superconducting materials for decades, or the young man in front of him who has broken through the record of high-temperature superconducting materials is stronger.

Upon hearing this, Xu Chuan smiled, but didn't care too much. It would be normal for those who do scientific research to have a heart that is unwilling to give in.

This chapter is not over, please click on the next page to continue reading! "It's OK, take it slowly, don't worry, if you want to retain the superconducting characteristics, you have to change some of its physical properties. This is no less difficult than redeveloping a new high-temperature superconducting material."

Zhang Pingxiang nodded and said, "It's okay, I came here just to make a breakthrough in the field of high-temperature superconducting materials. As long as there is hope, I can try it."

After thinking about it, he continued to ask, "If the zirconia doping effect is not good, do you have any other ideas?"

Upon hearing this, Xu Chuan thought for a while and said, "If you want to talk about your ideas, we have been studying this these days, and it is impossible to say that there is no. Compared to doping, I may be more optimistic about the coating."

Zhang Pingxiang thought about it and frowned slightly and said, "In the process of deposition of hard coatings in general ion plating reactions, there are often melt droplets. These melt droplets are present in the coating in the form of metal phases, which has a certain effect on releasing the internal stress phase of the coating to improve toughness."

"But the metal phase of the melted droplets is large (on the order of microns) and randomly distributed (without uniform distribution), which not only reduces the hardness of the coating but also significantly reduces corrosion and oxidation resistance. Therefore, it is not an effective method for toughening of hard and superhard coatings."

"If you want to enhance the toughness of high-temperature copper-carbon-silver composite materials through plating, it may be difficult to achieve. It can even destroy the surface crystal structure to a certain extent, causing superconducting failure."

"But since I have put forward this idea, there must be other ways, what is it?"

Xu Chuan smiled and said, "That's right, whether it is traditional plating methods or ion sputtering, it may not solve the toughness problem of high-temperature copper-carbon-silver composite materials. It may even cause doping problems due to plating."

"But we can change our thinking. Since the melting droplets will produce metallic phases, let it not be produced."

"And in traditional ceramic materials toughening methods, there is one such way."

Upon hearing this, Zhang Pingxiang blurted out and said, "Whiskers (fibers) toughen!"

Xu Chuan nodded with a smile and then said, "That's right, the mechanism of whiskers (fibers) toughening is that when whiskers or fibers are pulled out and broken, they consume a certain amount of energy, which is conducive to preventing the spread of cracks and improving the fracture toughness of the material."

"And the bonding of toughening materials with the original substrate is not a simple mixture. It is an organic composite that is organically combined through an extremely thin interface, and then the bonding strength between the interface and the substrate is improved."

"In this way, it should solve the problem of crystal structure damage of the raw material caused by the metal phase and doping of the melt droplet. In addition, its properties similar to thin film composite will not greatly affect the transmission of electrons of the superconducting material itself."

"But, I'm afraid I want to find the right toughening material."

Zhang Pingxiang took over the words and continued, "It may be very difficult. If you use whiskers (fibers) to strengthen toughness, the elastic coefficient of the material that plays a reinforcement must be higher than the original matrix; and the toughening must be compatible with the matrix."

"The first condition is easy to say, there are many materials with higher elastic coefficient than ceramic series materials; but the second condition is more troublesome, because the characteristics of superconducting materials, if compatible, may lead to superconducting energy gap failure."

Xu Chuan smiled and said, "You can only deal with one side and retain the integrity of the other side."

Zhang Pingxiang thought for a while and said, "It's true, but the single-sided treatment may not be that good. But for high-temperature copper-carbon-silver composite superconducting materials, as long as it can increase a certain coefficient, it is enough."

"This method may be feasible, but it only needs to be considered as the whisker (fiber) toughening material."

After touching the stubble on his chin, Academician Zhang fell into deep thought. After a while, he suddenly came to his senses and looked at Xu Chuan. "Since you have proposed this method, you must have thought about which material to use as toughening material, right?"

Xu Chuan nodded with a smile and said, "I have indeed considered it."

"What material?" Zhang Pingxiang asked quickly.

"Graphene!"
