Starting from a top student and marching towards the sea of ​​stars

Chapter 188 Scientific research is not just about qualifications

After completing the preliminary test, Cheng Zhong and Tian Shihao found Ning Chen together and exchanged the test results 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 were 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 then answered seriously:
"Academician Cheng, as you just said, we have solved many very difficult problems during the previous stage of research. These solutions have taught me a lot and also taught me a lot about steel smelting and processing. The details in the process..."

After a pause, Ning Chen continued:

"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.”

During Ning Chen's two years of experiments, he also experienced many failures. These situations are completely normal in the research process of scientific research projects.

"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 quite 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 inferred many conclusions just from the preliminary test results, 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. The final test results should basically correspond to what you just inferred."

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 knew that in addition to Ning Chen's strong talent, solid basic knowledge in various subjects also played a crucial 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 study.

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. However, it is not possible to enter the market immediately just relying on the existing properties of this material. To the application stage..."

In fact, for these problems, everyone already had an understanding of the situation when they participated in various testing tasks. However, they either only found some possible solutions to some of the problems, or they did not find any ideal solution.

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 plans for solutions 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 plans? If you have any ideas of your own, let us refer to them together."

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 that Cheng Zhong took the initiative to call her out, Ning Chen also said seriously:

"Academician Cheng, fellow experts, these plans have a very complete theoretical basis, and I also think they are very feasible. However, for some problems, I also have some other methods that can be tried."

Under everyone's expectant eyes, Ning Chen continued:
"Based on the experimental data of previous tests, you can find that during the smelting process of this kind of steel material, there is some decarburization phenomenon. Although this phenomenon is not serious, it still has a certain impact on the performance of the steel material. of."

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.

Everyone has already discovered the problem raised by Ning Chen, but there is no good way to completely solve it.

"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 that you can try vacuum heat treatment and vacuum tempering processes. In addition, we try to quench and cool the steel material to room temperature before performing low-temperature treatment to ensure complete martensitic 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 to strengthen the mechanical properties of steel materials while avoiding the appearance of other carbides, maximizing the strength, wear resistance, toughness and other properties of the material. …”

Next, Ning Chen gave several of his suggestions. Without exception, they all contained a lot of details. It would not be particularly difficult to verify the specific improvement effects.

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 fully thought about it just now. I also want to hear the opinions of experts first..."

Before Ning Chen could finish 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 couldn't compare with any member of the project team.
