Qingdao High-tech Industrial Park.

In the material testing laboratory of a factory.

After continuing to test another legendary anti-radiation material, Rupert Elve, who sat in front of the computer and called up the test data, said with emotion.

"It's perfect, it's incredible!"

Stanford Ralph, who led the team, did not ask where the incredible was, but asked Liu Feng straight to the point: "Professor Liu, what kind of material is this thing?"

"Metal nanocrystals," Liu Feng glanced at him lightly, and explained to all the foreign experts in the laboratory who were waiting for him, "To be precise, it is an evolved version of low-activation Cr martensitic steel!"

"Low-activation martensitic steel?" Looking at Liu Feng, Stanford Ralph frowned, and said with some surprise: "This is it?"

Apparently, for the name, he seems to have read the relevant papers.

It's just that because I haven't studied much metal materials, I can't remember where I saw it for a while.

To tell the truth, this material does not have the shiny metallic luster of a silver mirror, nor the attractive golden complexion of gold, and at first glance, it looks like ordinary steel, and it is quite difficult to touch with the hand, and it is not able to see where this material has the excellent properties of high temperature resistance and radiation resistance.

"That's it?" the old professor German, who was staring at the computer next to him, gave him a surprised look, "What do you mean by this thing? This material is already very powerful, right? At least, there is no one in the world that can be more suitable for use as an anti-radiation shell for nuclear reactions." ”

As he spoke, as if to prove it, he expertly knocked down a few buttons on his keyboard.

Soon, a scanning TEM image is displayed on the screen.

I saw that on that image, the gray-black patches were like an army waiting to be reviewed, interweaving layers of neat and delicate textures in the two-dimensional space of the plane, completely revealing the secrets of the unsightly thing on the nanoscale.

Pointing to several typical areas on the image, Rupert Hervé didn't explain much, and continued to speak: "Look at these places, do you understand?"

Leaning closer to the computer screen, Stanford Ralph followed the direction of his index finger.

I saw that between just 1-3nm, the almost spherical gray patch and the same spherical black patch, like a Taiji yin and yang fish, were tightly together.

Frowning, Ralph was shocked.

Even if he didn't study much about metal materials, he could see something unusual about it.

These two kinds of plaques, if he guessed correctly, should be two metal atoms, but under what circumstances did these two different types of earth atoms come together so closely and regularly?

Let's not talk about whether it's good or not, but whether it can be done.

Low-activation martensitic steel, Ralph has also recalled.

In the development strategy of energy, nuclear power itself is a direction that is difficult to ignore, and in nuclear power, the research and development of important structural materials used in key nuclear power equipment is definitely the key to the development of nuclear power technology, whether it is a nuclear power generation device or a nuclear waste treatment device, the structural materials of its key parts need to serve in extreme environments such as high temperature, strong irradiation and strong corrosion.

It's clear that low-activation Cr martensitic steel is the epitome of this type of material!

This structural material is capable of ensuring the safety of installations with heat flux densities of up to 10 MW/m2 and irradiation of up to 100 dpa/year.

However, although it has excellent radiation resistance, its high temperature strength is still relatively low, and the resistance to liquid Pb-Bi eutectic corrosion is poor!

The so-called metal nanocrystalline material of Huaguo people can make bonds between different metal nanoparticles, which not only ensures the anti-irradiation performance, but also enhances the high temperature resistance and liquid Pb-Bi eutectic corrosion resistance.

As far as he knows, all the current anti-radiation materials are not without being able to bond two metal nanoparticles together, but there is absolutely no one that can bond to such a perfect degree!

It is no exaggeration to say that the unsightly piece of material, the size of a fingernail, is a perfect work of art under a microscope.

Seeing that Liu Feng did not speak, Ralph continued in an emotional tone.

"Low-activation martensitic steel itself is more cutting-edge, but it is relatively unpopular, the reason is nothing more than the narrow scope of its application, but the technical difficulty is very great, in addition to the difficulty of research and development preparation, screening, preservation and industrial manufacturing are more difficult!"

"According to my understanding, even if we rely on 3D printing technology, the best metal powder is about 10,000 meshes, which is about 13 microns, although some laboratories can also achieve ultrafine powder of 15nm and below, but this powder has almost no way to be stored in a normal environment, let alone used to bond with another metal powder. ”

After all, in the physics of materials, the higher the mesh number of metal powders, the easier it is to oxidize, and the only two solutions that seem feasible are either to disperse it in a special way at the same time as the metal is smelted, or to mix it with another metal powder and spray it on a special substrate at the same time as the powder is generated.

Leaning back in his chair, Elvi sighed.

"As you can see, the difficulty of this thing is not only in the technology itself, but also in the implementation of the production process. ”

"In fact, the first wall structural materials with low activation characteristics designed and developed by various countries for nuclear fusion reactors, in addition to the low-activation martensitic steel of China, there are also Eurofer-97 steel from Europe, 9Cr2WVTa steel from country M, F82H and JLF-1 steel from Torayo, and the above steels have their own focus on performance, however, they cannot meet the requirements of high temperature resistance, radiation resistance, and liquid Pb-Bi eutectic corrosion resistance at the same time. ”

The experts around who had been exposed to the relevant materials also nodded, agreeing with Professor Elvi's statement.

"Even so, the difficulty of producing these materials has reached the horizon, and they can only be produced in small quantities in the laboratory at most, and the production process problems have always been difficult to solve, and this material perfectly balances these three properties, and can also be produced on a large scale to meet the needs of such a huge reactor, and it is no wonder that it can adapt to the development of controllable nuclear fusion devices. ”

Removing his gaze from the screen, the old Germanic man who was full of emotion turned to Liu Feng and asked,

"Professor Liu, the price of this material shouldn't be bad, right?"

No bandits?

Of course, the price of this material of the same weight is almost twice that of silver of the same weight, and the material used in such a reactor alone is almost 5 tons, which is 50 million small!

"Of course ......"

"Yes!" Before Liu Feng finished speaking, Elvi said to himself, "This material of the same weight is at least no worse than gold of the same weight, right? At least, if this material was available before, we would definitely be willing to buy it with the same weight of gold." ”

Liu Feng: "......"

Equal weight of gold, this is a bit exaggerated...... At most, it's twice the price of silver.

However, he opened his mouth, and in the end he did not explain further to this person.

In this way, it also lets these gringos know how much money is burned by controlled nuclear fusion, so as not to be wronged for us!

though

That's just the way it is......

Shrugged his shoulders, Liu Feng didn't explain too much on this issue, it's not too early, it's time for today's event to end, right?

After all, you can't seduce the interest of these gringos all at once, can you?

Of course, this guy will never admit that he is now thinking about his girlfriend, making money and doing research, this kind of life of wife and children is his favorite, so he has no patience to continue to fool around with these guys!

However, Liu Feng again underestimated the extent of these people's interest in advanced technology.

Elvi asked directly: "Professor Liu, can I ask you what method you used to do it? Do you use a special method to disperse it at the same time as the metal is smelting, or do you directly mix it with another metal powder and spray it on a special substrate at the same time as generating this powder?"

These people are really unforgiving!

Liu Feng frowned, he was a little impatient, what he would know in a short time, why did he have to figure it out on this day?

But this thing doesn't put itself in their shoes, what could be more hysterical for a scientist than a technology that can only be expected?

If it were him, he might have longed ten times more than all these people!

Looking at the old Germanic man with a face full of curiosity, and then seeing the team of more than 100 experts present who were also full of curiosity and eager to dig out his brain to find out, if he really wanted to pat his ass and leave, would these people tear him alive?

Shrugged helplessly: "OK! Of course, the latter method, we directly generate these two metal powders at the same time, and apply the two to a special substrate material for bonding, so that we can get this perfect material." ”

"Sure enough, it was the same as I had guessed. Elvi sighed, "I knew that only through special substrate materials could bond such a perfect configuration, and if I guessed correctly, this substrate material should be rhodium metal, right?"

Well?

Liu Feng glanced at the old Germanic man quite unexpectedly, and from just a few words, he actually guessed their key method correctly, and it was indeed worthy of the scientific elite selected from all over the world, which should not be underestimated.

With a solemn expression, he asked, "Professor Elvey, how do you know?"

The old man smiled and said disapprerovitically: "There is a special delocalized π bond in the rhodium metal explosion of the single atomic layer, which helps to stabilize its single-layer structure, is it difficult for a person who has been engaged in research in the field of metal materials for decades?"

Is it hard?

But this thing is the result of Academician Cui Kun's experimentation at a great cost!

This is a valuable experience that is difficult to exchange for thousands of dollars!

It can even be said that the value of this research result is no longer under the research of this anti-radiation material!

After all, anti-radiation materials are just one material, and the experience gained from developing this material can be used to develop more materials in the future, so that people can avoid many detours.

Seeing the disapprehensive expression on the faces of Elvi and many people around him, Liu Feng couldn't help but feel a lot of emotion in his heart, the depth of foreign material research is not something that he can make up for in a short time by developing several material research procedures.

In my heart, I put away my contempt for these people.

……

The visit is coming to an end.

Later, this group of foreign experts asked a lot of questions, and Liu Feng answered everything he could answer, and as for the part that was beyond the scope of the theory he knew, it was left to others to answer, or it was not answered at all.

Of course, in general, most of the questions are asked by foreign expert teams, and most of the hosts such as Liu Feng can answer, especially Professor Liu Feng and Liu Da, as well as the controllable nuclear fusion reactor and the two "perfect" materials, which make a group of proud foreign experts feel broken.

Stay in the high-tech industrial park until the evening.

When leaving, the person in charge took the initiative to get into the same car as Liu Feng, and couldn't help but sigh.

"Professor Liu, I really didn't expect that we in China would have such a day when we could conquer the gringos of the world with technology. ”

Liu Feng is not as optimistic as him: "It's a good thing to be able to convince the gringos with technology, but we can't be too happy! In terms of industrial technology, we can only be in the second gradient at most, and there are still many places that need to make up for it." For example, in the field of finishing and automation of country D, chip and system development of country M, etc., we still have a big gap to catch up. ”

It seems that he said a few words that were out of place?

Seeing the somewhat embarrassed expression of the person in charge, Liu Feng sighed, and finally turned the muzzle of the gun and said a few words of encouragement:

Of course, they are not gods, and we don't need to be presumptuous. There are many places where we have lost at the starting line in traditional industrial technology, and there is nothing to say, but at least in the field of new technology, everyone is groping for ways to find a way, and we are the same as their starting line, and we should not lose to others in these aspects!"

That's right, even without him Liu Feng, Huaguo has never lost to other countries in the field of emerging technologies! For example, laser technology, quantum technology, electromagnetic technology, etc., Huaguo has always been in the first echelon of the world.

However, now with him Liu Feng, Huaguo can not only maintain a leading position in these new technologies, but also be able to quickly catch up with the pace of the first echelon in traditional industrial technology - for example, materials, energy, etc., the results have gradually become prominent, and begin to affect the world!

As for the more distant future, and even the overall strength of the country's manufacturing industry, those things are really an extremely long process, and it is no longer something that Liu Feng can pat his chest to guarantee.

There are a lot of variables.

But for Huaguo, the only fatal variable is time!

Thinking of this, Liu Feng sighed, and suddenly advised the person in charge: "The construction of our Qingdao controllable nuclear fusion power station can be delayed, and even the longer it is delayed, the higher your merit will be......

“？？？”

The person in charge was confused.

He wished that the Qingdao controllable nuclear fusion power station would be completed as soon as possible, and then drive the gringos away.

The head is a little insufficient......
