Hand rubbing nuclear fusion live in the wilderness

Chapter 389 The material world that is about to take off
The high-speed cold-quenched nickel bricks were taken out of the equipment, and the surface was covered with various fragments, large and small, all over these nickel bricks.

These nickel bricks were displayed in front of the camera, which amazed the audience in the live broadcast room.

[Tsk tsk, good guy, it's all cracked. 】

[Emperor Crack! 】

[It's cracked, does it feel like this piece of metal is scrapped? 】

[So many cracks?Failed? 】

[This is even more heartbreaking than the Emperor's Crack that I spent 1000 million to cut out last time. If this crack is placed on jadeite, even beads can't be hit. 】

[Rapid cooling and quenching under high temperature, so many cracks are normal. 】

[A lot of cracks, anchor, is there something wrong with your smelting? 】

[I feel that these nickel bricks can be turned into powder with one punch. 】

【Upstairs, if you punch down, your hand will be broken by powder. 】

In the live broadcast room, the audience saw the nickel bricks that the Korean won took out, and they ridiculed and asked questions.

Han Won picked up a nickel brick, inspected it visually, and said with a smile: "It's normal to have cracks. This is an important step in the manufacture of gamma nickel."

"Nickel metal, like iron metal, has allotropes at different temperatures, but under normal circumstances, these allotropes disappear quickly."

"So when making gamma nickel, the first step is to bring pure nickel to a certain temperature, allowing the original nickel crystal structure to undergo morphological transformation."

"Just like iron atoms arranged into a face-centered cubic lattice between 912°C and 1394°C, called γ-iron, and above 1394°C, iron atoms rearranged into a body-centered cubic lattice, called δ-iron. "

"Both γ-iron and δ-iron are allotropes of iron, but when the temperature is lowered, the lattice structure of these allotropes will change again and return to the normal iron lattice."

"To make gamma nickel, the first step is to preserve these transformed 'hexagonal closest-packed' lattice structures."

"The easiest way here is to perform rapid cooling at the lattice temperature."

"Rapid quenching can reduce the high temperature of liquid nickel to tens of degrees in a short period of time. During this process, although the gamma nickel on the outside will re-transform into an ordinary nickel lattice, there will be some 'hexagonal nickel' inside the nickel brick. The closest-packed 'lattice nickel molecules are preserved."

"And what remains is the gamma nickel I need."

"This is the first step in the artificial synthesis of gamma nickel."

"And the second step is to extract the 'hexagonal closest-packed' lattice nickel molecules inside these nickel bricks."

Hearing that, someone in the live broadcast room couldn't help asking.

[Gamma nickel is the same as γ-iron and δ-iron. When the temperature is lowered, these lattice structures will change and return to a normal lattice, so the extracted 'hexagonal closest-packed' lattice nickel molecules will not Will it decay back? 】

Han Yuan glanced at the barrage and said with a smile: "This question is very interesting and very good."

"The hexagonal closest-packed 'lattice nickel molecules, also known as gamma nickel, like gamma-iron and delta-iron, will also revert to the ordinary nickel lattice when the temperature drops below the lattice point."

"Even if it is fixed inside the nickel brick by rapid cooling and quenching, after a period of time after extraction, it will also return to an ordinary lattice."

"So, how to preserve gamma nickel at normal temperature is a key step in smelting and synthesizing gamma nickel."

After a pause, Han Yuan continued, "Smelting gamma nickel involves five steps in total."

"The first step: under a fixed temperature and pressure, transform ordinary nickel lattice molecules into 'hexagonal closest-packed' lattice nickel molecules and perform rapid quenching to preserve them."

"The second step: separate these preserved gamma nickel from ordinary nickel."

"The third step: do special treatment to the isolated 'hexagonal closest packing' lattice nickel molecules, and preserve them."

"The fourth step: further processing the preserved 'hexagonal closest packing' lattice nickel molecules to turn them into gamma nickel metal powder."

"The fifth step: the last step, the refined gamma nickel metal powder is smelted into a gamma nickel metal plate through a special powder metallurgy metal."

"These five steps are the steps to smelt gamma nickel."

"Of course, this is just a general idea, and each of these five steps has many details and points that need attention."

"For example, in the first step, the purity of raw materials must reach 90.00% or more, and a vacuum smelting furnace with adjustable temperature and pressure is required."

"Another example is the special agent and environmental requirements used in the second step to separate the 'hexagonal closest-packed' lattice nickel molecules from ordinary nickel lattice molecules."

"These are areas that need attention and cannot be ignored."

"Because if it is ignored, it will cause the overall smelting step to fail."

As soon as Han Yuan's voice fell, there was a lot of noise in the live broadcast room.

【It’s so troublesome, it’s about purity, it’s also a vacuum, and it’s also about controlling the degree of oxidation. 】

[It’s gone, it’s gone, this can’t be done at home. 】

[The host's equipment is estimated to be several million in size. 】

【millions?I don't mind if you add a zero. 】

[Isn't it normal that the manufacturing process of materials that can be used in controlled nuclear fusion is troublesome? 】

[The above statement is reasonable, otherwise controllable nuclear fusion would have been researched by us long ago. 】

[A material needed in controlled nuclear fusion, the smelting process is so complicated, no wonder there has been no progress in controlled nuclear fusion until now. 】

[It sounds complicated, but in fact, any modern alloy smelting steps are no less than this. 】

For ordinary viewers, the smelting steps of this new allotropic gamma nickel are extremely complicated.

Not only are there many processes, but also there are various requirements for smelting equipment and smelting environment.

And these are just the general steps, and the details in each big step are more and more cumbersome.

After all, for ordinary audiences, basically 90.00% of people above nine do not know the steps of alloy smelting.

Many people even think that smelting alloys is actually very simple.

It is as simple as throwing two or three metals into the furnace, heating, melting, stirring, pouring out and cooling to form an alloy.

The audience with this kind of thinking is actually not one or two, but a rather large group of people.

Therefore, it is embarrassing for Han Yuan to come up with such complicated smelting steps.

Of course, in the eyes of various countries, the more detailed the Korean won is explained, the more they like it.

The more detailed the explanation, the less effort it will take for them to reproduce it.

Among the scientists squatting in the live broadcast room, there are many experts in the material field,

As soon as the five steps were outlined, all the experts were amazed.

They have never thought that alloys can be smelted in this way, and no one has ever thought that allotropes can be transformed and manufactured in this way.

According to past history and experience, although the alloy smelting steps are more complicated than ordinary people imagine, they are not so complicated.

Leaving aside the detailed steps of smelting alloys such as quenching, cooling, lattice solidification, and material ratios, the audience in the live broadcast room actually did not have too many problems.

At its most basic level, smelting alloys is actually melting two or more alloys into a furnace.

It's just that in order to make the alloy meet the required requirements, the steps in smelting will be much more detailed.

Without knowing the core smelting steps, it is almost impossible to copy and decipher an alloy.

For example, the famous "Yuanchu Laboratory" launched the CFA copper-iron alloy in the past two years. The smelting steps are carried out through different ratios of copper and iron and different smelting methods.

Once this bimetallic single-formula multi-adaptive alloy came out, it caused a huge sensation in the whole world.

The impact on the alloy industry is no less than a magnitude [-] earthquake.

In just two or three years, tens of billions of new markets have been created, and countless alloy material companies have closed down because of CFA copper-iron alloys.

This has made countless countries and financial groups jealous, wanting to imitate or decipher.

But without knowing the core smelting technology, even if the raw materials of CFA copper-iron alloy are only copper and iron, it is not so easy to decipher.

At least until now, no country or company has been able to successfully imitate it.

Even many research institutes can't even make the two metals of copper and iron perfectly fused together.

Because the solid solution and segregation properties of copper and iron are very different, it does not mean that the two metals are melted in the furnace and then stirred for cooling.

Yuanchu Lab firmly controlled the core technology and patents, which made these people unwilling and helpless.

And this is only two common alloys of copper and iron, so it is so difficult to decipher.

Needless to say, the gamma nickel smelting process being broadcast live now.

If a detail is not noticed, then the copying will definitely not go on.

Therefore, during the Korean won live broadcast, experts from various countries stared at the display screen carefully.

For fear of missing any details.

Especially this new way of making allotropes.

It seems to have opened up the two veins of Ren Du, an expert in the material industry.

Let everyone exclaim: "It turns out that allotropic materials can be manufactured in this way."

In fact, in reality, there are quite few allotropes of metals, except for those naturally radioactive metals.

Just like iron, although there are three allotropes of γ-Fe, δ-Fe and α-iron, it can only be preserved under specific conditions.

Once the storage conditions drop to the critical point, the metal lattice will gradually transform into an ordinary metal lattice.

However, the allotropes of iron, such as γ-Fe, are actually quite widely used because the face-centered cubic lattice is softer, more volatile, and more malleable than the original iron.

Unfortunately, the storage temperature of γ-Fe is between 912°C and 1394°C. If it is lower or higher than this temperature range, it will turn into other iron.

Scientists also tried to preserve γ-Fe at room temperature, but they couldn't.

Even if it is known that γ-Fe can be partially preserved in the iron ingot under rapid cooling, the material industry cannot completely separate γ-Fe from ordinary iron.

And even if pure γ-Fe in the core area is collected, there is no way to preserve it for a long time.

For this reason, experts and researchers in the material industry have tried various methods, such as low-temperature storage, high-temperature remodeling, such as immediately fusing γ-Fe into other alloys, and so on.

But none of these methods worked.

After a period of time, the lattice of γ-Fe will change automatically and transform into ordinary iron.

In this process, whether it is pure γ-Fe or an alloy smelted using γ-Fe, there will be changes such as embrittlement and slag, which will eventually lead to the scrapping of the entire material.

They found a way to preserve gamma-Fe for a long time.

This is also the reason why all experts in the material industry are looking forward to it after hearing the five steps of smelting gamma nickel.

Everyone wants to know how this anchor preserved gamma nickel, an allotrope of nickel metal.

Can this method be applied to other metals?
Such as iron.

The properties of nickel and iron are actually quite close, and both are iron series elements.

If applicable, the high-temperature allotropes of iron, γ-Fe and δ-Fe, can also be preserved.

Then the development of the material industry will usher in a huge, even earth-shaking change.

And if the material industry takes great strides forward, then the technology of the whole world as a whole will have a pair of wings.

Han Yuan didn't pay much attention to the ridicule in the live broadcast room and the outside audience.

After smelting all the smelted nickel bricks, he quickly transferred them and sent them to the grinding machine.

In an abrasive mill, these cracked nickel bricks are broken open, broken into small pieces, and then ground into a finely divided nickel powder.

Like the iron allotropes γ-Fe and δ-Fe, the time for γ-nickel to be solidified in nickel bricks by rapid cooling is also limited.

And the existence time is much shorter than that of γ-Fe and δ-Fe.

γ-Fe and δ-Fe can exist for about five to six days in ordinary iron ingots, while the existence time of γ-nickel in nickel bricks is only one to two days.

So once you start smelting, you must hurry up and deal with it.

The longer the delay, the more 'hexagonal closest-packed' lattice nickel molecules are converted to ordinary lattice nickel molecules.

It would take some time to grind all the nickel bricks into nickel powder. Han Yuan sat and waited, watching the barrage and chatting with the audience.

The audience in the live broadcast room were very puzzled by the behavior of South Korean won grinding nickel bricks into powder, and this kind of question was the most frequently asked.

Seeing such puzzled questions on the screen, Han Yuan smiled and said: "The purpose of grinding nickel bricks into nickel powder is to better extract the 'hexagonal closest-packed' lattice nickel molecules in the nickel bricks.

"Although after being ground into powder, the 'hexagonal closest-packed' lattice nickel branch will be doped with the nickel molecules of the ordinary lattice, making it difficult to distinguish."

"But there is still a way to extract the 'hexagonal closest-packed' lattice nickel molecules out of it."

Saying that, Han Yuan got up and took a triangular narrow-mouth bottle from the tool table in the workshop, which contained more than half of the bottle of light red solution, and the bottle was blocked with a stopper.

"Inside this bottle are the key items that will be used next."
