Chapter 188 Scientific research does not just rely on qualifications
After completing the preliminary test, Cheng Zhong and Tian Shihao found Ning Chen together and exchanged the results of the test with Ning Chen.
“Judging from the current test results, the steel materials we processed and synthesized are relatively qualified. Many process problems that we thought were not easy to solve before have now achieved breakthroughs.”
Ning Chen did not deny what Cheng Zhong said. To be honest, these specific processes are indeed very difficult. If it were not for the presence of these experienced steel material experts, Ning Chen would not be able to carry out the experiment at all. .
"Ning Chen, what do you think of the current test results?"
After hearing Cheng Zhong's question, Ning Chen thought for a moment and replied seriously:
"Academician Cheng, as you just said, we solved the problem during the previous stage of research. These solutions helped me learn a lot, and also allowed me to understand a lot of details in the steel smelting and processing process..."
After a pause, Ning Chen continued:< br>
“Of course, if we only judge based on the measurement results, there must be a certain deviation between the material structure we processed and the designed material structure. But after all, this is only the first stage of the experiment. Such a result is also a very normal phenomenon.”
In the past two years of experiments, Ning Chen has also experienced many failures. These situations are also repeated in the research process of scientific research projects. Nothing more than normal.
"Ning Chen, what impact do you think these deviations in material structure will have on the performance of materials?" Cheng Zhong asked.
“These effects are relatively comprehensive. Issues such as passivation treatment, heat treatment, and the proportion and method of adding chromium elements will affect the corrosion resistance of steel materials. Microstructural issues will affect The maximum fatigue resistance of the material. The distribution of fine grains and extremely fine metal carbides will affect the wear resistance and toughness of the material..."
Ning Chen only learned from the preliminary test results. Many conclusions were deduced, which surprised both Cheng Zhong and Tian Shihao.
Realizing that his statement was a bit absolute, Ning Chen quickly added:
"These are just my inferences. The final results can only be obtained through further testing."
"Well, more detailed tests will definitely continue. But I think what you said, Ning Chen, is very reasonable, and the final test results should basically correspond to your inference just now."
As Cheng Zhong said, after the project team conducted more detailed and comprehensive tests on the steel materials they processed, Ning Chen's previous inferences came true one by one.
This made Cheng Zhong and Tian Shihao feel that Ning Chen seemed to have the super power to predict the future, which was very incredible.
But they also know that in addition to Ning Chen’s strong talent, solid basic knowledge in various subjects also plays a vital role.
From the few days of contact with Ning Chen, they can feel how serious and hard-working Ning Chen is towards scientific research and learning.
Ning Chen was not satisfied that his guess was correct. In fact, when doing the subsequent testing work, Ning Chen was already thinking about how to solve these problems.
After all, finding the problem is only the first step. If you cannot come up with a good solution, the entire research will still be in a stalemate.
After completing all the testing work, Cheng Zhong called everyone together again to summarize the previous testing work and discuss how to solve some of the current problems.
“What makes us happy is that after a stage of experiments, the steel material product we prepared can still restore our previous design plan very well. But just relying on this material has the existing Attributes cannot be entered into the application stage immediately..."
In fact, for these problems, everyone has already understood the situation when participating in various testing work, but they may only find out some of the problems. Some possible solutions were found, or no ideal solution was found.
After summarizing all the problems, Cheng Zhong, Tian Shihao and others put forward some of their own ideas and discussed them with everyone.
During this period, Ning Chen was not in a hurry to express his thoughts, but quietly listened to everyone's plans and analyzed the feasibility of these plans.
After everyone discussed for a while, some solution plans have been agreed upon.
But Cheng Zhong discovered that Ning Chen did not put forward any ideas of his own. Cheng Zhong knew that Ning Chen could not have thought about the solutions to these problems, so he took the initiative and said:
"Ning Chen, what do you think of these solutions? If you have any ideas of your own, let us join in. Please refer to it.”
Hearing what Cheng Zhong said, everyone focused their attention on Ning Chen.
The several process improvement plans proposed by Ning Chen last time were of great help to the progress of the research, which made everyone more trustful in Ning Chen's ability.
Seeing Cheng Zhong take the initiative to point out his own, Ning Chen also said seriously:
"Academician Cheng, fellow experts, these plans have very complete theoretical basis, and I also think they have a high level of But for some problems, I also have some other methods that I can try.”
Under everyone's expectant gaze, Ning Chen continued:
"Based on the experimental data of previous tests, you can find that there is some decarburization phenomenon during the smelting process of this kind of steel material. Although This phenomenon is not serious, but it still has a certain impact on the performance of steel materials. "
The so-called decarburization refers to the phenomenon that the surface carbon content of steel is reduced during the heating process.
The decarburization phenomenon will affect the mechanical properties of the steel surface, preventing the steel from reaching the ideal hardness.
As for the problem raised by Ning Chen, everyone has discovered that there is no good way to completely solve this problem.
"Ning Chen, we have considered this problem before, but it is indeed difficult to completely avoid it. During the steel smelting process, if the temperature is not enough or the high temperature duration is too short, it will be difficult to complete the entire steel smelting process. "
"Academician Cheng, my suggestion is to try the vacuum heat treatment and vacuum tempering process. In addition, we try to quench the steel material to room temperature and then perform low-temperature treatment to ensure complete. Martensite transformation..."
Ning Chen listed many detailed conditions, including specific tempering temperature and tempering time, the ideal temperature change curve for low-temperature treatment, etc.
“In this way, in theory, nano-scale metal carbides can be dispersed and distributed, strengthening the mechanical properties of steel materials, while avoiding the appearance of other carbides, improving the strength, wear resistance, and toughness of the material. All the other properties can be maximized..."
Next, Ning Chen gave a few of his suggestions, all of which contained a lot of details. He wanted to verify the specific improvement effects. It's not particularly difficult.
After listening to Ning Chen's thoughts, Cheng Zhong couldn't help but said:
"Ning Chen, no wonder you didn't speak before. It turned out that you were waiting to summarize at the end."
Hearing what Cheng Zhong said, the members of the project team couldn't help but smile.
If they were not familiar with Ning Chen, they would definitely not be able to laugh at this time. After all, Ning Chen is just a student now, and his qualifications cannot be compared with other experts.
But after so many days of living together in experiments, everyone liked Ning Chen very much.
Ning Chen not only has strong professional ability, but also has a very humble personality and does not show any arrogance.
Everyone is working together for the same goal. Having a team member like Ning Chen will undoubtedly play a vital role in the progress of the project.
Ning Chen didn’t know what others were thinking, so he quickly waved his hands and explained:
“No, no, Academician Cheng, it’s just that I haven’t thought about it completely just now, and I want to hear it first. The opinions of experts..."
Before Ning Chen finished speaking, Cheng Zhong interrupted:
"Okay, Ning Chen, you don't need to explain so much. I think it's good that you always summarize at the end of every meeting. Your ideas are very comprehensive, and no one else can compare with you in this regard. ”
Ning Chen was a little frightened by Cheng Zhong’s praise. After all, in terms of qualifications, Ning Chen could not compare with any member of the project team.
