Hand rubbing nuclear fusion live in the wilderness

Chapter 393 Completion | Nickel Smelting
Not only the audience in the live broadcast room were interested in how KRW stabilized the 'hexagonal closest-packed' lattice nickel powder.

Scientists and researchers from various countries are more interested.

This is not just a material that can be applied to controlled nuclear fusion.

It is a brand-new allotrope smelting method, and it is also a method suitable for manufacturing allotropes of metal materials.

This is even more worthy of attention.

As we all know, the formation of allotropes is a macroscopic reflection of an element with more electrons in the outermost shell and various bonding methods.

But this does not include most metal elements and rare gas elements.

Because of the stability of the atomic structure of metal elements and the singleness of the bonding mode of hydrogen and halogen of rare gas elements, it is difficult for them to form allotropes.

That is to say, most metal elements and rare gas elements have no allotropes.

If this method of artificially smelting and synthesizing nickel's allotrope 'γ-nickel' can be applied to other metal materials, every scientist knows what it means.

It is even no exaggeration to say that this will be a revolutionary step in the history of human material development.

The live broadcast room was very lively. Han Yuan glanced at the barrage and said with a smile: "The 'hexagonal densest packing' lattice nickel is actually gamma nickel, but the refined ones cannot be preserved for a long time."

"The next thing to do is to process it so that it can be stored at room temperature and pressure for a long time."

"This step is the most critical step in the smelting of gamma nickel."

"And it must be carried out within twelve hours after the 'hexagonal closest-packed' lattice nickel is extracted."

"The faster this step is, the better, otherwise the extracted 'hexagonal closest-packed' lattice nickel will gradually convert to ordinary lattice nickel."

After thinking about it, Han Yuan added another sentence:
"Of course, in a short period of time, the 'hexagonal closest-packed' lattice nickel can still maintain its own lattice coefficient stability."

"The stabilization time is about twelve hours."

"After all, if the lattice coefficient is not stable enough, then no matter how it is refined, there will always be impurities in the gamma nickel that is finally smelted."

"After more than twelve hours, because the internal tension of the γ-nickel lattice is insufficient, the outer electrons of the nickel element will begin to flow or transfer, and eventually they will gradually fall into ordinary lattice nickel."

As he spoke, Han Yuan put the collected 'hexagonal closest-packed' lattice nickel into a high-temperature-resistant crucible.

The crucible filled with nickel metal was returned to the furnace again and calcined again.

This is the first step, and the most unexpected step.

According to previous human experience in synthesizing various alloys, after a certain alloy is synthesized, such as the "steel" in iron alloys, it needs to undergo different degrees of reforging and quenching according to its different uses.

But this recalcination and quenching are often at a temperature close to the melting point of the material itself.

For example, for steel, the most common reforging temperature is more than 900 degrees and more than 100 degrees, which is already close to the melting point of steel.

But the first recalcification temperature of 'hexagonal closest-packed' lattice nickel is beyond everyone's imagination, including him.

At first, when Won saw the gamma nickel smelting steps, he almost thought that the system gave him fake data.

How could the temperature of the first recalcination be more than 400 degrees and less than [-] degrees?

To be precise, the temperature for the first reforging of 'hexagonal closest-packed' lattice nickel is between '457.3°C-482.5°C'.

The temperature of this re-forging in the furnace surprised the Korean won at first glance.

It's not that he hasn't smelted alloys before, and he has read a lot of alloy smelting information, but this is the first time he has seen such a low alloy smelting temperature.

Although the melting point of "hexagonal closest-packed" lattice nickel is more than 200 degrees lower than that of ordinary lattice nickel, its melting point is also [-] degrees, which is not too low.

When he saw the reforging temperature of more than 400 degrees for the first time, Han Yuan even suspected that this temperature had no effect on the 'hexagonal closest-packed' lattice nickel. It was the second and third conditions that were at work.

There are three conditions for the first re-calcination of 'hexagonal closest-packed' lattice nickel.

The first one is to maintain the recalcination temperature between 457.3°C-482.5°C'.

The second condition is to keep the pressure in the calciner at 3.5 standard atmospheres.

Oh, by the way, what needs to be mentioned here is that the re-calcination of the 'hexagonal closest-packed' lattice nickel powder is not carried out under vacuum, but under the protection of inert gas.

This is different from converting ordinary lattice nickel smelting into 'hexagonal closest-packed' lattice nickel.

The third condition is power on.

That's right, the third requirement for the first reforging of 'hexagonal closest-packed' lattice nickel is electrification.

The inert gas filling the reaction furnace and the reaction crucible need to be energized at the same time.

Moreover, the current and voltage strengths of the two are different when they are energized.

If it is reasonable to say that the first condition maintains the temperature of re-calcination is much lower than normal re-calcination, after all, it also belongs to the category of high-temperature re-calcination.

Then the third condition directly overturned Won's perception of alloy smelting steps.

He has obtained this system for several years, and has read and studied a lot of knowledge about alloy material smelting, but he has never seen that alloy material smelting requires electricity during the reforging process.

This incomparably novel smelting method made Han Yuan very interested. After careful study, he realized that whether it is high temperature, high pressure, or electrification, it is a means to maintain the stability of the lattice in the 'hexagonal closest-packed' lattice nickel.

If any one of the three conditions is missing, the 'hexagonal closest-packed' lattice nickel cannot be affected.

But if the three conditions happen to happen together, then the lattice stability coefficient of 'hexagonal closest-packed' lattice nickel will be greatly improved.

Therefore, the furnace for smelting and re-calcining 'hexagonal closest-packed' lattice nickel needs to be specially customized, not only to provide a high-temperature environment, but also to have good confidentiality performance.

In addition, the furnace needs to be powered.

This series of requirements are all concentrated on one smelting furnace, which can kill any manufacturer.

When South Korean Won carefully read and studied this material, he admired the person who invented this method of smelting gamma nickel and stabilizing the lattice coefficient of the 'hexagonal closest packing' lattice nickel, and was astonished.

He didn't know what kind of brain hole that scientist or researcher had to come up with this method.

This smelting process is full of twists and turns, and it is even more difficult to find than a narrow path. The cliff is not something that normal people can research.

But when Won explained how to stabilize the lattice coefficient of the 'hexagonal closest-packed' lattice nickel in the future, the audience in the live broadcast room were dumbfounded.

[Fuck?Alchemy needs electricity? 】

[What the hell, I can understand the use of inert gas for protection. It may be to prevent oxidation, but what is the situation with electricity? 】

[Can the lattice coefficient of a metal be stabilized by electrification? 】

[This step, every step is beyond my expectation, I never thought there would be such a thing. 】

[Extremely complicated material science, sure enough, in comparison, we still have a long way to go. 】

【too strong! 】

[I was thinking about how such an amazing and complicated smelting process was discovered or thought up. The smelting alloy needs to be electrified. This is probably unprecedented. 】

The audience in the live broadcast room sighed and discussed.

Even though there are many students and experts in the field of materials science among the tens of millions of people in the live broadcast room, they are still surprised by the extremely complicated smelting method displayed by Won.

Especially when it comes to metal smelting.

For the current countries, in fact, there are only a few types of metal smelting and alloy smelting methods within a rough range.

Like extracting metals from raw ores, the general methods are nothing more than physical sorting, electrolysis, thermal reduction, and thermal decomposition.

And the smelting of alloys is even simpler.

Generally speaking, the alloys used in industry are relatively precise, and there are roughly three smelting methods for them.

They are vacuum induction melting method, electric arc furnace smelting method, and ingot casting technology.

Among them, vacuum induction melting is more suitable for the smelting of advanced alloys.

Its characteristic is that under the condition of relatively high-quality raw materials, it can smelt alloys with higher purity and less gas content, and precise chemical composition control.

Like aviation aircraft, rockets, satellites, etc., the alloys used in many precision equipment on them are smelted by vacuum induction melting.

For relatively large bearings such as automobile bearings and some ship keels, ingot casting technology is generally used.

This kind of qualified alloy skeleton that can be ingot cast in one place is more suitable for bearing greater torque and greater pressure.

Of course, no matter what kind of alloy smelting method, the steps of reforging and stress release are inevitable.

Although the residual stress of alloy parts cast by some methods such as powder metallurgy is very small, in order to make the overall properties of the alloy meet the requirements, these steps will only be more, not less.

The methods such as reforging and releasing residual stress are actually to stabilize the lattice coefficient and molecular state in the alloy parts, so that they can maintain stability for a long time.

As for the method of using current, temperature, and pressure to maintain a crystal lattice that cannot be stabilized under normal temperature and pressure explained by the anchor in the live broadcast room, they have never heard of it.

Didn't even think about it.

This kind of whimsical approach is simply beyond what ordinary people can think of.

Not to mention the ordinary viewers in the live broadcast room, even these experts are ignorant about whether this method can maintain the lattice coefficient of the 'hexagonal closest-packed' lattice nickel.

Unless they are experts who happen to be studying allotropes or metal lattice transformations, most experts basically cannot understand the specific principles and electronic conversion coefficients.

But what everyone in the studio knew was that since this method was used by the anchor and explained in such detail, it must be useful.

And the effect should be quite good, otherwise, with the character of this anchor, I wouldn't introduce it in such detail.

The audience and experts in the live broadcast room were confused, and they kept sending various bullet screens to ask about the principle and detailed process.

But the won has no time to care about these.

The 'hexagonal closest-packed' lattice nickel powder in the furnace is undergoing the first re-calcination firing, which requires him to keep an eye on various changes and control various external conditions.

Even the control of the magnitude of the current needs his control.

Now KRW is already busy with the back of his head. This time he will pay attention to this indicator data, then he will pay attention to that data indicator. He also needs to sum up various data and calculate them in his heart to see if they meet the standards.

The first reforging of 'hexagonal closest-packed' lattice nickel is the most frustrating.

Once a certain external condition is not well controlled, the entire furnace of "hexagonal closest-packed" lattice nickel will fail to be forged and scrapped.

This process is actually more suitable for artificial intelligence to control.

It has all kinds of strict data for reference and control, unlike some traditional industries.

For example, firing porcelain with firewood requires a master craftsman with decades of experience to control it so that the best ceramics can be fired.

The "hexagonal closest packing" lattice nickel smelting is different, it is more in line with the precise processing procedures, as long as the various set parameters are kept stable during the manufacturing process, there is almost no possibility of failure.

So it is more suitable to use artificial intelligence to control the whole process.

As long as standard control is given, and it is within the range that machines can do well, artificial intelligence can definitely do better than most people.

The human body structure and the way of thinking of the brain are destined to be more suitable for creative work.

In the simulation space, Han Yuan carefully controlled various parameters in the processing plant and controlled the reaction conditions in the furnace.

Time passed bit by bit, until the controller next to the smelting furnace made a 'ding' sound, and he breathed a sigh of relief.

There was no time to relax, and after waiting for the re-calcined 'hexagonal closest-packed' lattice nickel powder in the furnace to completely cool down, Han Yuan immediately started the follow-up inspection and processing.

However, the most difficult step in the whole process of artificially smelting and synthesizing gamma nickel has passed. There are no mistakes in the whole process, and the rest is much simpler.

Working from early in the morning until three o'clock in the middle of the night, the processing of the first batch of gamma nickel was finally roughly completed.

The reason why it is said to be preliminary is because the processed gamma nickel is still in powder state.

However, the particles in this powder state are still relatively coarse, which does not meet the requirements of powder metallurgy, and further grinding is required in the follow-up, and then pressed into nickel plates or nickel bricks through powder metallurgy technology.

However, there is no need to worry too much. The 'hexagonal closest-packed' lattice nickel powder that has completed the lattice coefficient stabilization process can already be stored, and will not degrade over time.

Therefore, the compression molding of gamma nickel powder can be done at any time later.

However, considering that it needs to use a relatively special powder metallurgy technology, South Korean won decided to finish it as soon as possible.
