Before returning to the college entrance examination, I became popular in the science circle

Chapter 132
At the discussion meeting, based on the superior data of T4 titanium-aluminum alloy, they could predict that the data of T5 special blades would not be bad. But when the simulation data was really displayed in front of him, it was undoubtedly more intuitive and impactful, making him impatient and wanting to The materials must be prepared immediately and tested on the tester to check the data of the real materials.

I am as anxious as South China, everything is ready, and now I just need to start work.

"Chengxu, arrange the personnel in place, I can't wait!"

"Teacher, Academician Xie, let's start the experiment!" Wu Tong nodded firmly, and the group entered the laboratory and began to operate step by step according to the preparation process.

A new material, not to mention the research and development and design of the material, often requires a lot of exploration and experimentation before it can be formed. The preparation process must go through continuous trial and accumulation before it can be put into production. Two or three It can be arranged and put into production every month, which is super fast.

However, this process, under Wu Tong's deduction, is like pressing the fast forward button, the time is infinitely compressed, and the detailed process can be accurately specified.

However, even Wu Tong, before actually getting started with the experiment, she can only determine to use a certain process, and specific parameters, such as temperature, time... can only be used in the experiment, and she can really get in touch with the experiment process and control it on the spot , to determine the most accurate data.

The clock keeps turning without stopping, the passage of time is ignored by busy people, the experiment is slowly coming to a later stage, and the theoretical model is gradually becoming a reality.

The high-temperature melting and casting of the reaction furnace is the official nickel-iron blade material of their experiment. Wu Tong combined titanium in it to make up for the deficiency of the nickel-iron material and achieve the effect of a composite material, so it was named T5.

The core technology involved in this experiment is single crystal directional solidification.Single crystal superalloy technology can eliminate grain boundaries, maintain excellent comprehensive mechanical properties and structural stability at high temperatures, and meet the design requirements of high thrust ratio engines. Its manufacturing technology has become the core technology for preparing advanced engines. Academician Xie officially stated this Big boss in the field.

"Superalloy, as the alloy material of single crystal blade specimen, has extremely high requirements for fixed pulling speed, simple step pulling speed and multi-step pulling speed. We have used single crystal blade specimen temperature field, paste Numerical simulations were carried out on the growth of the zone and solidification structure, and directional solidification experiments were carried out. Finally, it was concluded that the alloy material with good single crystal integrity can be obtained by using low-speed fixed drawing and multi-step drawing speed, and high-speed fixed drawing and multi-step drawing speed. Single crystal material specimens will generate stray crystals on the edge plate under simple step pulling speed."

Academician Xie carefully explained the core points of single crystal technology to Wu Tong. This is the core point that their team worked hard to find through repeated experiments and failures.

However, at this moment, Academician Xie did not hide anything and taught Wu Tong in detail.

For such an outstanding child, he hopes that he can use these few skills as a small stepping stone for this child to move to a higher peak, and also lead China Materials to a peak that they have not reached!
With gratitude, Wu Tong carefully absorbed some knowledge and turned it into his own mastery.

"Teacher, increase the temperature of the reactor to [-]!"

Seeing that Cheng Huanan was operating at a parameter of two thousand degrees Celsius. After receiving more in-depth guidance, Wu Tong further intuitively deduced that this was not the most accurate temperature and needed to be increased, otherwise it would cause internal damage to the metal. Unevenness will eventually affect the failure of the synthesis, which is barely successful and cannot reach the optimal data.

Cheng Huanan did not hesitate, and operated according to Wu Tong's instructions. The leader of the experiment was Wu Tong. Naturally, he had to follow Wu Tong's ideas. His empiricism was not needed. The leader could only have one voice, otherwise the experiment would not be carried out. Finish playing early, this is also a good time to cultivate the control of Wu Tong's laboratory.

He acted as the child's teacher. In terms of materials, the basic knowledge that could guide her was some basic knowledge. He thought about other aspects, and he would think more about this child.

"It's ready. Mr. Xie and Brother Ruan, get ready for directional solidification!" Wu Tong looked calm and was ready to stare at the reactor. At the most suitable time, he cooperated with Academician Xie to start operating it.

The furnace is first turned on, and then the directional solidification step is operated according to the planned temperature gradient.

The main points were just popularized and emphasized by Academician Xie, and Academician Xie led them to teach the operation almost hand-in-hand. They successfully completed all the details and avoided the turbulent flow of the internal liquid during the solidification process of the molten metal. High-speed solidification method, in stable operation, constantly adjust the drawing speed, and stabilize the process for solidification...

In the end, with careful, exquisite and stable operation step by step, they finally took out several pieces of blade material with a metallic blue-black color and shimmering silver light from the coagulator, with some mysterious beauty.

Once formed, they directly completed the shape of the blade in one step. This is the material deduced for the blade. Naturally, the blade model can best test the real data.

"That's it, perfect, no stray crystals!" Academician Xie gently stroked the surface of the material, which felt as smooth as a baby's skin.Putting aside everything else, this directional solidification operation was perfect.The experiment of being able to condense materials has been more than half successful, and now all that remains is to test and compare the performance.

But based on experience alone, he can feel that this material is unspeakably superior.

The tensile machine was put on first, and the tensile resistance data rose rapidly, easily crossing 1000MPa. Looking at the data that was still rising, Cheng Huanan and Academician Xie looked at each other, and it was self-evident that they were excited. When did the tensile resistance of the material Is it so easy for sex to break through 1000 and become a daily routine?
The final data was fixed at 1710MPa. Both the operators and the testers were so shocked that they could not speak for a long time. This was another final test data that surpassed the simulation data. Is this also going to become my god's practice?Can this also become a routine?My God, I am truly a magical material man!
Followed by mechanical property tests one by one, from room temperature creep performance, mechanical fatigue performance, thermal fatigue performance and impact resistance, and then various properties at high temperature, as well as high temperature plasticity...

Followed by hot corrosion resistance and oxidation resistance testing...
The high-temperature melting point test shocked all the experimenters. The instantaneous over-temperature directly approached the unimaginable high temperature limit of 3000°C. It has an extremely high initial melting temperature, and the material structure is extremely stable and can withstand high temperatures below 2400°C for a long time. impact.

Ultra-high thermal conductivity, ultra-low thermal expansion coefficient and the lowest possible density, the physical properties are so good!
This is really the blade material they dream of!
