If Chen Nian is a giant beast that created a mountain, then they are like worker ants one by one. Although they are not very powerful, they gradually build a spectacular ant nest.

Chen Nian could only admire this.

——

But having said that, if you can save unnecessary duplication of work, you should still save it.

So, he opened his mouth and said:

"No matter what, you should think about it carefully."

"I do have a direction that I can try."

"You know, there is an important hydraulic system on the aircraft carrier, which is the hydraulic system of the arresting cable. There is still relatively little research in the country."

Soon, the teacher blew the whistle for everyone to gather. After the physical education class, Chen Nian really didn't get any inspiration from Qiu Mai.

It seems that the previous two times were coincidences, and Qiu Mai does not have any special "luck" attributes.

However, Chen Nian cannot be said to be disappointed.

After all, whether it is study or scientific research, it is something that must be done step by step and down-to-earth. If it is really so easy to take advantage of opportunities, will the development of science and technology be so difficult?

After the physical education class, it was already past 5 o'clock. The three of them went to the cafeteria to eat together. They were silent all the way. Chen Nian originally planned to go back to his residence and continue to study advanced functional materials, but then he thought about it and took the silicon material metallurgy course.

I have finished learning, but many of the practical details mentioned in it have not been verified.

So, he simply called a car and headed in the direction of the Western Materials Research Institute.

His idea is very simple. In fact, he just wants to touch the equipment and verify what he has learned.

At this moment, in the Western Material Research Institute.

"Still not working? Adjust the relative density to about 55% and try again?"

"It's useless. We have just tested the relative density of 57%. There is no need to test the same range repeatedly."

"So what exactly is the problem? Initial temperature? Raw material particle size? Heating rate?"

"I don't know. I don't understand. Have the results of differential thermal analysis come out?"

“It came out, but it’s of no use and I can’t see the problem.”

Several researchers were discussing in low voices around the failed prototype, while Guo Qi couldn't help but have a look of disappointment on his face.

Of course, he is not disappointed with the young people under his command, nor is he disappointed with materials science. What he is disappointed with is that his luck is really bad!

This time they plan to trial-produce molybdenum disilicide, which is a high-temperature anti-oxidation coating widely used in the aviation field. It is generally used in turbine engine components, burners, tail nozzle seals, and is also used in electric heating.

Components on automobile spark plugs.

In short, it has a wide range of uses and great effects.

But now, there is no mature manufacturing method in China.

Generally speaking, SHS technology is used to manufacture molybdenum disilicide, which is self-propagating high-temperature synthesis technology.

But the problem is that human exploration of this technology is still relatively limited, and the influencing factors and synthesis mechanism are not fully understood.

Therefore, what they can do is to further explore based on the existing knowledge.

For example, typically, an increase in the relative density of reactants can promote an increase in reaction temperature and self-propagation speed.

For another example, the thickness of the powder will affect the reaction process.

But no one knows exactly what density, thickness, and initial temperature to use.

This also resulted in the trial production progress being stuck in the trial and error stage and unable to move forward.

This project has been stuck for 6 months since its inception, and so far, there has really been no results.

Although this is the normal rhythm of materials science research, Guo Qi can't help but feel a little unwilling as he watches other projects come to fruition one after another.

Damn it, I won’t do anything with materials in my next life.

This thing is too basic.

It's hard work and thankless, no matter how nice you say it, if you can't produce results, who will remember you?

Thinking of this, Guo Qi sighed, walked to his students, and said:

"Okay, if it doesn't work today, just continue tomorrow. This thing is all about luck."

"Oh, by the way, I will give you a day off tomorrow. Whoever has nothing to do can go up the mountain and see where there is a temple. Go and ask for help."

Hearing Guo Qi's words, everyone had a helpless smile on their faces.

They all knew that Guo Qi was joking, but they could also see the sadness behind the joke.

Why go to the temple to ask for help?

It sounds nice, but who can I go to the temple to ask for?

Taishang Laojun?

Hey, don't tell me, this thing is really professional.

It seems that I will have to bring a statue of Laojun here some other day. If I have nothing to do, I will burn some incense and pay my respects.

"Boss, are you really going to have a day off tomorrow? The project is so tight, so why don't I give it up? I have nothing to do."

"I don't have anything to do. I'll come back tomorrow to get ready. When you come back, you can start doing experiments directly."

"What are you preparing? Pelleting?"

"For granulation, the raw materials must be prepared. If you can steal some time, just steal some time."

"I feel like this is useless. If I really try my luck, when will it happen?"

As soon as these words came out, everyone fell silent again.

yes.

Although modern materials science does involve luck, most of the time, it still relies on theoretical guidance.

Their problem now is that the theory is too weak, so weak that it basically cannot form any guiding significance.

The only solution is to accumulate data through a large number of experiments and analyze the best path through modeling, thereby increasing the probability and reducing the difficulty of "trying your luck".

It can only be overcome by time.

When will it end?

There were neat sighs in the laboratory, and after a moment, someone said:

"It would be great if there was a way to circumvent the shortcomings of the SHS method."

"Don't push your luck, just get it right in one step, find some new process, and cover all the defects."

Hearing this man's words, the others couldn't help but roll their eyes.

"Why don't you want to win 100 million in the lottery? When the time comes, we will hire a bunch of people to do experiments, and they will be reckless."

"Yes, I think the probability of winning 100 million is relatively high."

Everyone was teasing each other one by one, and the atmosphere finally became more relaxed.

As soon as their emotions recovered, everyone began to prepare and continue the experiment. But at this moment, a voice suddenly sounded at the door of the laboratory:

"There is such craftsmanship."

"The combination of SHS and processing can solve the problem."

"SHS-pressurization, SHS-extrusion and SHS-extrusion methods should all work."
