The next day, Li Zhao said hello at the rolling mill, and in recent days, he will mainly focus on the material factory, and in the next few days, the time he can spend in the rolling mill will be relatively limited. It is estimated that the time of each day will be to review the drawings or something, and some other progress can only be delayed, after all, the commissioning of the material factory is the next major event.

As for the tricycle or something, Li Zhao doesn't have time to care at all, whoever cares about it, after all, mass production has been completed, and the rest is the problem of production and personnel management. As for the later report, just take the time to look at it yourself, it really needs to be improved. You must know that Director Yang of this project has been punished, if there are still people who want to be perfunctory and poke out a new basket, this Director Yang will not have to stay.

When he came to the material factory, Master Zhang took Li Zhao to meet the people of the Metal Materials Research Institute first, which is also the proper meaning, Li Zhao is not often here, and he has not seen these people. The person in charge is surnamed Liu, he is not young, he is in his forties, and he still came back from abroad, Li Zhao knows that this is the top talent of this era.

In order to let them know the current situation of the material factory, the core information of metal materials was also opened to the main personnel of the research institute, but after reading it, these people were impressed, it was too many achievements, and they felt that they only had to look up. And Dean Liu directly gave up the position of dean and volunteered to be the vice president, but Li Zhao did not plan to take this position.

After the two sides met and greeted, Dean Liu also took Li Zhao to visit their laboratory, which was indeed very simple, Li Zhao originally thought that there would be a spectrophotometer or something, but there was no here. There are only all kinds of glassware, test tube racks, iron racks, etc., and there are no advanced instruments. Li Zhao didn't even see the most basic magnetic stirrer, let alone any advanced instruments, Li Zhao had nothing to say except sighing.

At this time, Li Zhao no longer had any hope for Su's father's idea of applying for instruments from his superiors, if he could apply, would these people not apply? Obviously, there is no way to get these instruments, and in the future, except for making them yourself, it is basically impossible to have the opportunity to get them directly in a short period of time, especially many of them are still the most advanced.

Dean Liu also saw Li Zhao's disappointed look at this time, but he had no choice, so he didn't care about these at this time, and directly asked what he was interested in: "Chief Engineer Li, can you tell us how to carry out the next work?" We've been working on it for so long, and we haven't come up with any decent recipes. Not to mention that there is no such thing as now, the performance of metal materials can be edited into a book, for each user to choose and use at will, and your gap is too big, and the next research we will listen to you, to ensure that where to play. ”

Li Zhao is also embarrassed, although he knows how to study, but now the formulas he comes up with are all tested after sixty years, and some of them are simply bought by the boss of the original factory. I didn't dare to say that I researched it myself, and I always didn't say anything about this matter, and few people really dared to ask me anyway. After all, the things Li Zhao took out were too shocking, so I hadn't heard of them anywhere.

And everything about Li Zhao can stand up to investigation, there is no abnormality, in the end, apart from the speculation of Heavenly Grant, where can there be any other reason to explain? If you want to talk about spies or something, these are not available in foreign countries, which spy is stupid and can give away his good things? Now in the face of Dean Liu's question, Li Zhao can only explain the original understanding and point out the research direction.

After a deep sigh, Li Zhao also wanted these people to start working, because there is really no difficulty in ingredient testing now, and it is really a waste of talent for these people to be busy. So he said: "That's fine, then let's find a conference room to talk about this matter, and also find the future research direction for our research." I hope that the results can be produced as soon as possible, and it will also make a name for our metal research institute. ”

After all, Li Zhao has the knowledge after 60 years, and there are many detailed information about the formula, Li always doesn't worry about nothing to say, so he said directly: "Everyone knows that metals are generally polycrystalline, and it is rare to see single crystals, so there is a process of metal heating and melting that gradually softens and finally becomes liquid." ”

Therefore, we should understand that in these polycrystalline structures of metals, some crystal structures are temperature-resistant, and some crystal structures are not temperature-resistant, and in order to achieve temperature-resistant effects, it is necessary to transform the crystal structure in the metal into temperature-resistant crystal structures as much as possible, or directly into single crystals with temperature-resistant structures. Therefore, in the future, our biggest research direction will be to study the crystal structure of metals and how to achieve this crystal structure. ”

Listening to Li Zhao's words, Dean Liu looked stunned, yes, these people actually study more methods of metal or try, don't care about anything, fuse together first and then talk about others. This is also the usual method of materials research, commonly known as a blind cat hitting a dead mouse. But in the future, this approach is becoming less and less used, as it is time-consuming, costly, and less likely to produce results.

To put it mildly, this method of trying your luck may have been touched 10,000 times, but you haven't encountered just the right one, which is also a very normal thing. Therefore, research that relies on luck is becoming less and less important, and more research is to study the theoretical basis first, and then find out the corresponding results based on the theoretical basis.

As a result, most of the research has been invested in the study of structure, and after discovering an excellent structure, it is often possible to convert the metal into this structure as much as possible, and then study the performance, which can often get good results. Li Zhao continued: "Alloys are different, alloy metals will also form crystal structures, but obviously the crystal structures will be more complex, and some will also form special defect structures, which may bring new properties. ”

"So this research is long-term and extremely boring. I hope that everyone can be mentally prepared for the next research, which is destined to be a long-term work, and the research results will not be published in a short time. You should have read the booklet you got, there is only a code on it, the ingredients are not marked, the use is tracked throughout the process, that is, the crumbs need to be recycled, these are all confidential. ”

Next, Li Zhao began to explain the various stacking structures of metal atoms, and also analyzed the advantages and disadvantages of various stacking structures, as well as the laws of various stacking changes with temperature and other conditions. Then Li Zhao said: "After listening to this, everyone should understand the direction of our research, and what we lack most now is what kind of means to use to observe these structures. I think we all understand that we need to find a way to build an X-ray diffractometer that will allow us to know the crystal structure of metals and provide clear guidance for our research. ”

Then Li Zhao introduced the principle and implementation method of X-ray diffractometer, which is definitely a big killer for everyone, because it will directly change their research methods. In fact, this is also the limitation of this era, the microscopic cognition is still in the era of speculation and empirical evidence, and the research method provided by Li Zhao can directly increase the speed of this research by dozens or hundreds of times.

To give a simple example, let's say that everyone is familiar with the lubricating oil, we all know that this is a single-chain alkane, olefin, with the increase of chain length, the temperature resistance will increase, but this temperature resistance is obviously limited, because after a certain temperature, this single-chain structure will be broken. In order to study more temperature-resistant lubricating oils, some people have proposed a double-chain structure, that is, directly turning a single chain into a ladder-like double-chain, so that the temperature resistance can be greatly increased.

With this guiding direction, a batch of lubricating oil with double-chain structure has appeared, which has outstanding performance in temperature resistance, and has good performance at low pressure, so it is also mostly used in aerospace. This is the difference between the research structure and a large number of empirical tests, one is to go straight to the goal, the other is to pass a large number of tests, and the efficiency of the two is to make a judgment, which is why Li Zhao urgently needs experimental instruments.

After explaining these, Li Zhao took out the formulas that were already in production and explained them in detail. These are what Li Zhao has seen in the future, especially the formulas he bought, many of which give the crystal structure of the formula. In particular, some of the formulas that Li Zhao has not come up with now, including single crystal structure, have special requirements for production conditions.

After some explanation, Li Zhao was unreserved, and told all the research theories he knew, which were all core secrets. These people are their own team in the future, whether they can produce results, study various formulas thoroughly, and based on these formulas, research more and better formulas, you need to rely on these people to work.

Seeing that Li Zhao finished speaking, there was warm applause in the conference room, and then Master Zhang also woke up, there was no way, what Li Zhao said was completely a book from heaven to him, he knew every word, but when it was linked, he didn't understand a word, and then he saw Li Zhao looking at himself and smiled awkwardly.

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
