Chapter 0098 The First Stage of the Positive Blade Dislocation Theory, Breakthrough!
this day.
Mu Jingchi continued to repeat the boring experimental research.
A master's student walked next to him, a graduate student in his research group, wearing thick glasses.
The glasses graduate student was followed by other graduate students, but their eyes were all focused on the glasses graduate student. I saw that his face was red, and his expression was very unnatural, as if he was suppressing something.
"Mr. Mu, my experiment seems to have succeeded. ”
Since Mu Jingchi became a teaching assistant, most students have called him Teacher Mu. Although Mu Jingchi, like them, is at the graduate level, Mu Jingchi already has a teaching status.
Well?
Mu Jingchi pulled out his consciousness from his material analysis, and his eyes froze, "What did you say?"
"My experiment looked like it had worked. ”
Immediately, Mu Jingchi's face turned pale, and Mu Jingchi's expression was very serious, "What do you mean by looking like you have succeeded, either you succeed or you fail." There is no swing in science, don't you know if there is success? Won't the data be looked at? Won't the model be analyzed?"
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 as a teacher of the school, I can't blindly live in peace with my students.
Especially in scientific research, Mu Jingchi, as the person in charge and core of the research group, must also have his own prestige.
was shouted by Mu Jingchi like this.
The body of the graduate student with glasses trembled, and immediately responded, "Mr. Mu, my experiment was successful, and it is in line with the model characterization 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 trust your own instincts, trust the data you make yourself. ”
"Let's go, I'll go and see. ”
When he came to the graduate student's laboratory next door, Mu Jingchi saw the material that had been formed.
In terms of combined material properties, this is a failed material. However, the current experimental research is not aimed at conquering new materials, but experimental research to verify the dislocation theory.
Yes, although in terms of performance, it is a failed material. However, it is a very important material in terms of current projects.
"Has the material analysis been done?"
When Mu Jingchi opened his mouth to ask, he also went down to the field and began to do material analysis.
"We have already done it, X-ray diffraction, electron scanning electron microscopy and transmission electron microscopy material analysis methods, we have done it all. ”
"Based on the data obtained, the model is established, and the resulting model matches the data model formed by dislocation theoretical analysis. ”
Returning to the familiar experimental environment, the spectacle graduate regained his composure. He first pushed the glasses on the bridge of his nose, and then replied very quickly.
Mu Jingchi listened to the words of the graduate student with glasses and nodded, but his eyes fell on the data of the analysis system in the computer screen.
From top to bottom, from left to right, Mu Jingchi looks carefully while using his recent knowledge of mathematics, physics, and the mechanics of materials in 2100.
A look of joy had begun to appear on his face.
However, for the sake of insurance, Mu Jingchi personally went through the material analysis.
The computer is equipped with a special X-ray diffraction analysis operating system, which is a rich and can be expanded and modified at any time to operate the powder diffractometer and diffraction analysis practical software system.
It is composed of two 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, and the diffraction data processing and analysis module is integrated by some commonly used diffraction pattern processing programs.
These procedures can be used for qualitative analysis of X-ray diffraction phases, quantitative analysis of X-ray diffraction phases, peak processing, grain size measurements, determination of precision lattice constants, and measurement of crystallinity.
Of course, this is just an X-ray diffraction analysis.
Later, it is necessary to do the electron diffraction and diffraction contrast analysis of the transmission electron microscope, as well as the backscattered electron diffraction analysis.
Although X-ray diffraction analysis can obtain macroscopic statistical information about the crystal structure and orientation of materials, it cannot correspond to the microstructure and morphology of materials.
However, the transmission electron microscope can combine electron diffraction and diffraction contrast analysis to realize the microstructure and morphology observation of materials and the micro-region correspondence of crystal structure and orientation analysis, but the information obtained is often micro-regional and local, and it is difficult to carry out statistical analysis with macroscopic significance.
The backscattered electron diffraction technique combines the characteristics of X-ray diffraction statistical analysis and lens-electron microscope electron diffraction micro-analysis, which is a supplement to the analysis of crystal structure and crystal orientation of X-ray diffraction and electron diffraction.
The three are combined with each other.
You can get a huge amount of relevant data.
This is the data that belongs to the material analysis, and then the data is processed on the basis of the relevant diagrams and models, which is used for characterization.
The more representations in the experiment, the better, and if these representations match the representations of the theoretical analysis, then the accuracy of the theory is verified.
"We've made it!"
Mu Jingchi's knowledge system is replenished at a rapid pace every day, and he has extremely strong logical ability for the analysis and reasoning of data models.
It didn't take too long for Mu Jingchi to affirm the consistency between material characterization and theoretical characterization.
All of these are experimental studies based on the theoretical idea of positive blade dislocation proposed by Mu Jingchi. It is enough to prove the accuracy of the theoretical idea.
Then, Mu Jingchi slowly stood up and turned around.
Looking at the graduate student's hope to be affirmed, he solemnly announced the successful breakthrough of this experimental research!
Yes!
Yell!
Not only the glasses graduate students, but the other three graduate students and Ai Xiaosheng, who had missed it before and had just arrived, fell into ecstasy together.
There was an extremely intense excitement on everyone's face and in their eyes.
"You start by organizing the experimental design, the experimental protocol, and the experimental data. When everything is sorted out, you can write relevant papers, and these papers are stable in the first area of SCI. ”
Mu Jingchi's words were full of joy, and he said that he was very satisfied with the few graduate students in front of him.
"But don't get carried away either. This is only the first stage of the theory of positive edge dislocation, and the next two stages are more difficult. ”
In order to prevent them from being too wild, Mu Jingchi persuaded them with words again.
It is impossible to directly verify the entire theory of positive edge dislocation, because this theory will also change due to the change of material molding process, and can only be verified in three stages.
It corresponds to the three processes of material deformation, recovery and recrystallization.
"Teacher Mu, don't worry. We are also confident in the next two stages!"
The four graduate students who have just experienced success are full of vigorous self-confidence and are full of energy!
"It's good to have faith, find a time for us to celebrate. Mu Jingchi drew an arc, "Just celebrate with the material fracture and damage research group!"
