The Literary Life of a Science Leader

Chapter 98 The first stage of positive edge dislocation theory, breakthrough!
this day.

Mu Jingchi continued to repeat boring experimental research.

A master's student, who is a graduate student in his research group, walked by, wearing thick glasses.

The graduate student with glasses was followed by other graduate students, but their eyes were all focused on the graduate student with glasses.I saw that his face was blushing, and his expression was very unnatural, as if he was suppressing something.

"Teacher Mu, my experiment seems to have been successful."

Since Mu Jingchi became a teaching assistant, ordinary students called him Teacher Mu.Although Mu Jingchi is in the postgraduate stage like them, but Mu Jingchi already has the status of a professor.

Ok?
Mu Jingchi withdrew his consciousness from his material analysis, his eyes were fixed, "What did you say?"

"It looks like my experiment worked."

Immediately, Mu Jingchi's expression became serious, "What does it mean to seem to be successful? Either it succeeds or it fails. There is no swing in science. Don't you know if there is success? Don't you know the data? Models Can't analyze it?"

Professor Hetian taught together, and the other party also gave him a lot of relevant educational knowledge.

As the person in charge of the research group and also as the teaching staff of the school, I can't blindly get along with my students peacefully. Praise when I should praise, but I must be strict when I should be strict.

Especially in scientific research, Mu Jingchi, as the leader and core of the research group, must also have his own prestige.

He was yelled at by Mu Jingchi.

The spectacled graduate student trembled and responded immediately, "Teacher Mu, my experiment was successful. It conforms to the model representation of theoretical analysis."

Mu Jingchi nodded, and said to him: "No matter what others think, you have to believe in yourself. Even if you don't believe in your own intuition, you still have to believe in the data you made."

"Go, I'll go and have a look."

Coming to the graduate student's laboratory next door, Mu Jingchi saw the materials that had already formed.

In terms of comprehensive material properties, this is a failed material.However, the current experimental research is not aimed at conquering new materials, but at experimental research to verify the dislocation theory.

Therefore, even in terms of performance, it is a failed material.But judging from the current project, it is a very important material.

"Has the material analysis been done?"

When Mu Jingchi opened his mouth to ask, he himself went off and began to do material analysis.

"It has been done, X-ray diffraction, electron scanning electron microscopy and transmission electron microscopy material analysis methods, we have done it."

"A model was built based on the data obtained therein, and the resulting model matched the data model derived from dislocation theory analysis."

Returning to the familiar experimental environment, the glasses graduate student regained his composure.First he pushed up the glasses on the bridge of his nose, and then answered very quickly.

Mu Jingchi nodded when he listened to the words of the glasses graduate student, but his eyes fell on the analysis system data on the computer screen.

From top to bottom, from left to right, Mu Jingchi looked very carefully, and at the same time used the mathematics, physics, and material mechanics learned in 2100 to analyze.

A look of joy had begun to appear on his face.

However, to be on the safe side, Mu Jingchi personally analyzed the materials.

The computer is equipped with a special X-ray diffraction analysis operating system, which is a practical software system for powder diffractometer operation and diffraction analysis that is rich in content and can be expanded and modified at any time.

It consists of two major functional blocks: the diffractometer control operation module, which is mainly used to control the operation of the diffractometer and complete the collection of diffraction data; the diffraction data processing and analysis module is integrated with some commonly used diffraction pattern processing programs.

These programs can perform X-ray diffraction phase qualitative analysis, X-ray diffraction phase quantitative analysis, peak processing, grain size measurement, precise lattice constant determination and crystallinity measurement, etc.

Of course, this is just X-ray diffraction analysis.

Later, electron diffraction and diffraction contrast analysis of transmission electron microscopy, as well as backscattered electron diffraction analysis are required.

Although X-ray diffraction analysis can obtain the macroscopic statistical information of the crystal structure and orientation of the material, it cannot correspond this information to the microstructure of the material.

However, the transmission electron microscope combines electron diffraction and diffraction contrast analysis, which can realize the observation of material microstructure morphology and the micro-area correspondence of crystal structure and orientation analysis, but the information obtained is often micro-area and local, and it is difficult to carry out macroscopic analysis. Significant statistical analysis.

Backscattered electron diffraction technology combines the characteristics of X-ray diffraction statistical analysis and lens electron microscopy electron diffraction micro-area analysis, and is a complement to X-ray diffraction and electron diffraction crystal structure and crystal orientation analysis.

The three are combined with each other.

A large amount of related data can be obtained.

This is data that belongs to material analysis, and then is processed based on these data to obtain relevant diagrams and models for characterization.

The more experimental characterizations, the better, and if these characterizations match those of theoretical analysis, it is equivalent to verifying the accuracy of the theory.

"We succeeded!"

Mujingchi's knowledge system is being supplemented at a rapid speed every day, and he has extremely powerful logical ability in the analysis and reasoning of data models.

It didn't take too long for Mu Jingchi to affirm the consistency of material characterization and theoretical characterization.

All of this is experimental research based on the positive edge dislocation theory proposed by Mu Jingchi.It is enough to prove the accuracy of the theoretical thinking.

Afterwards, Mu Jingchi stood up slowly and turned around.

Looking at the graduate student's hopeful eyes, he solemnly announced the successful breakthrough of this experimental research!

yeah!
Shout out!

Not only the glasses graduate student, but also the other three graduate students and Ai Xiaosheng, who had just arrived after missing it before, fell into ecstasy.

Everyone's face and eyes showed extremely strong excitement.

"You first sort out the experimental design, experimental procedures, and experimental data. After everything is sorted out, you can write related papers. These papers will be published in SCI District [-]."

Mu Jingchi's words were full of joy, looking at the few graduate students in front of him, he expressed his satisfaction.

"But don't get carried away. This is just the first stage of the positive edge dislocation theory, and the next two stages are more difficult."

In order to prevent them from being too wild, Mu Jingchi used words to persuade them.

The entire positive edge dislocation theory cannot be directly verified, because this theory will also change due to changes in the material forming process, so it can only be verified in three stages.

Corresponding to the three processes of material deformation, recovery and recrystallization.

"Teacher Mu, don't worry. We also have confidence in the next two stages!"

The four graduate students who have just experienced success are full of confidence and are in high spirits!

"It's good to have confidence, let's celebrate together sometime." Mu Jingchi draws an arc, "Just in time to celebrate with the material fracture and damage research group!"
