Mu Jingchi has always disliked words to persuade others.

Because when taking a firm stance or self-awareness, speech will appear very weak and pale. But it is much more powerful to persuade with practical actions.

It's still the same small conference room.

Mu Jingchi sent down the experimental plans of the master's students one by one, with some annotations made by him.

As if he was in a good mood, Mu Jingchi's expression was no longer a cold look, but a half-way smile, "You are all very good, you have your own ideas, and you put them into practice." ”

"I've seen all the experimental protocols, and they are innovative, some things work, some things don't, but overall they reflect the talents of each of you. ”

"That's something I really value. ”

Mu Jingchi praised them with a smile on his face, even if these plans did not work, but the exploration of ideas was commendable.

Even the classmate who used the rare metal sword to go sideways is not simple, you know, rare metals are not just something that can be used casually, how to use rare metals well, but a university asks.

"Let's talk about your proposal now. ”

This time the meeting was more formal, everyone sat down around the long table, and Mu Jingchi spoke. With the various annotations in the experimental protocol, he also needs to explain them one by one, and prove that their experimental protocol is not feasible with unshirkable facts.

After the last meeting, the master's students also have a little understanding of Mu Jingchi's character.

Although he looks cold on the outside, he is still very talkative, not harsh, serious, and cold.

Flipping through their experimental protocols, they began to discuss some of Yu Jingchi's annotations, and they were still very serious about this.

On the one hand, it is for the subject, and on the other hand, it is also for learning.

Doing projects with bigwigs who are stronger than themselves can always learn something, which is one of the purposes of their research group in Mujingchi.

Mu Jingchi would go home every day, and the study room shrouded in the aura of the system greatly improved his knowledge.

Mu Jingchi, who has already seen their experimental plan, can be said to be handy about this. Everyone's questions are answered, clearly organized, from shallow to deep, from small to big, and meticulous.

The four master's students began to have back and forth with Mu Jingchi, but gradually became good students who took notes, as if they were listening to an academic report.

From this time on, they really admired Mu Jingchi.

Sometimes material research does depend on luck, and some materials with strong performance also rely on luck to break through, so Mu Jingchi will also be looked down upon.

It is believed that its previous material project was also a coincidence of luck.

But now they feel that this is not the case, and Mu Jingchi, a straight doctoral student who was awarded the 'National Outstanding Youth Award', is really expected.

The academic circle is still different from those literary circles, whether it is strong or not, and how much stronger, can basically be seen from real discussions, and there is no uncertainty.

For materials science, there is no mystical theory to prevaricate. If you can't, if you can't, if you can't, it's about the same as math.

It's not that it can be pretended, if there is no goods in the stomach, the filling will be exposed in three clicks or two.

"Doctor, what's your plan?"

At this time, they also understood Mu Jingchi's plan, but after being convinced, they did not reject it, and asked Mu Jingchi. There was curiosity and exploration in their eyes, and they wondered in their hearts where Mu Jingchi's experimental plan came from?

Mu Jingchi glanced at Ai Xiaosheng next to him.

So, Ai Xiaosheng hurriedly projected the experimental plan that had been prepared in the laptop.

"My direction is dislocation. ”

Mu Jingchi began to manipulate the documents in the computer and narrate them to the master's students.

In real conditions, even at 0K, not all atoms in the crystal of the material are arranged strictly periodically, because there are some small regions in the crystal, and the periodic arrangement of the atoms is destroyed in these regions or when passing through these regions.

Such areas are called crystal defects.

Crystal defects are divided into point defects, line defects, surface defects, and bulk defects.

Regardless of the type of defect, the concentration is very low. However, the effect of defects on crystal properties is very large. It affects the mechanical, physical, chemical and metallurgical properties of crystals.

Dislocations, on the other hand, are line defects.

Dislocation is one of the most important defects in crystals, which has a great impact on the properties of crystals, especially metal crystals, especially mechanical properties.

As soon as they heard Mu Jingchi's words, the faces of the four graduate students suddenly became solemn.

Without him, dislocation is the focus of metal materials. At the same time, dislocations are really very difficult, and the theories are very rich, and some concepts and properties are difficult to understand.

The average student and material worker only understands certain applications of dislocations qualitatively or semi-quantitatively. As for the detailed and quantitative analysis and discussion, it is basically necessary to read specialized monographs and literature.

"Our aluminum alloy project is mainly based on the three strengthening mechanisms of aluminum alloy, which changes the movement of dislocations, hinders the movement of dislocations or obeys the movement of dislocations at the right time, and achieves the control of the movement of dislocations. ”

"In this way, the goal of manufacturing high-strength aluminum alloys is achieved. ”

Mu Jingchi showed his experimental plan, which has more detailed theoretical elaboration and calculation analysis, so that these master's students can also have a general impression.

As for convincing them immediately, Mu Jingchi didn't think about it.

Mu Jingchi's theory of dislocation should actually be regarded as a completely new theory, but it is actually still cohesive with the existing dislocation theory.

For example, the high strength of 18Cr-8Ni stainless steel comes from the fact that the alloying element Ni atoms are separated in the laminar fault region of the extended dislocation, forming a Suzuki air mass, which makes it difficult to slip and climb the dislocation.

Another example is the strengthening mechanism of high-strength nickel-based superalloys lies in the presence of ordered precipitated phases Ni3 (Ti, Al).

In order to transition from the above theory to Mu Jingchi's theory, it needs to be verified by experiments and supported by data, so that it is truly convincing.

If the previous scientific research results were practical materials, then this time the results are a new dislocation theory.

If Mu Jingchi wants to develop a new aluminum alloy material, then this new dislocation theory must be borrowed from his hand and shown in the "Fundamentals of Materials Science (2069 Edition)" fifty years later.

The dislocation theory in it will also be named Mujingchi.

Perhaps in future textbooks, Mu Jingchi's dislocation theory will become an independent small chapter.
