Chapter 837 Expanded Alloy

Yang Dongsheng immediately thought of the usefulness of this thing!

A few days ago, they were still worrying about how to withstand the high temperature of 1700 degrees, and under the strong centrifugal force of tens of thousands of revolutions per minute, they could not be thrown off like noodles.

Now there are trillions of tons of nickel-iron alloy in front of him, which is still safe at a high temperature of more than 6000 degrees.

If these alloys were really as Yang Dongsheng speculated, they would be of great use.

In addition to being used to make high-pressure turbine blades for aero engines, it can also be used to make impellers for pumps that work in harsh environments, such as canned pumps for nuclear reactors.

The current nuclear reactor canned pump, the impeller is made of tungsten alloy or depleted uranium alloy.

There are also high-tech fields such as the tail nozzle of the rocket engine and the drill bit of the drilling rig.

Yang Dongsheng also saw in the data that a neutron star is a special star that can still be superconducting at a high temperature of hundreds of millions of degrees, which is the real high-temperature superconducting.

The high-temperature superconductivity claimed by scientists from various countries actually refers to superconductivity above minus 196 degrees, that is, above the boiling point of liquid nitrogen.

The heat inside the alloy continued to pour out, and the slurry formed by the diamond kept tumbling.

At that time, the ejected solids must have expanded and melted.

Yang Dongsheng searched upwards, and finally found a diamond with a length, width, and height of more than ten kilometers at a depth of about 1100 kilometers.

Yang Dongsheng cut another piece of nickel-iron alloy that was half a meter long, five centimeters thick, and ten centimeters wide.

Because liquid oxygen is an important raw material for steel production, and liquid nitrogen is a by-product of making liquid oxygen, the content of nitrogen in the air is 78%, and oxygen is only 21%.

It took a long time for Yang Dongsheng to raise his head again. At this time, the tumbling slurry in the diamond had stopped.

But when the two come into contact, the diamond does not gasify.

And after expanding, it seems to become a piece of ordinary nickel-iron alloy.

Yang Dongsheng could imagine that there must have been thick steam rising over there, and the pot was boiling.

Yang Dongsheng's mind suddenly flashed, thinking of those nickel-iron alloys that were sprayed out deep underground.

This piece of nickel-iron alloy was actually broken into two pieces.

As long as it can reach room temperature superconductivity, it is more than enough to make nuclear magnetic resonance equipment, electromagnetic catapults, electromagnetic guns, superconducting energy storage equipment... More than enough!

Fortunately, while the alloy is heating the glacier, it is gradually cooling itself.

Why do you need to check the boiling point of liquid nitrogen?

It didn't take long for the glaciers in contact with the alloy to change from direct gasification to melting, and the speed of melting became slower and slower.

If you want to understand the reason, then solve the problem according to the problem.

The alloy expanded by about 50% last time, and the original shape can no longer be seen.

Yang Dongsheng couldn't wait to get a piece back and try it out.

Taking advantage of the alloy not moving anymore, Yang Dongsheng locked onto the nickel-iron alloy, and soon he was disappointed again—the alloy still swelled.

It's just that the shapes of those metals were irregular, and Yang Dongsheng was shocked by the solid objects pouring out of the ground, so he didn't notice.

The reason is that after the alloy is sprayed out, as the temperature drops, the surrounding pressure also decreases.

A huge sense of frustration rose from the bottom of his heart.

This piece of nickel-iron alloy finally sank seven or eight meters in the glacier before it stabilized.

Second, the pressure is maintained while the alloy cools.

First, replace the cooling medium.

Put the alloy in the center of this diamond, and it's a few kilometers thick diamond on either side.

Just like last time, the alloy sank.

It wasn't until this time that Yang Dongsheng realized that something was wrong.

Yang Dongsheng looked at a diamond about 2800 kilometers underground.

Diamond is an extremely compressive substance. Studies have shown that diamonds can maintain their original structure even in the face of high pressures equivalent to those at the center of the earth.

Then due to the higher density, it slowly sank deeper.

Although these nickel-iron alloys on the earth cannot be compared with those on neutron stars, they can really superconduct at high temperatures of hundreds of millions of degrees.

Just when Yang Dongsheng was about to exit the [-]D map, he suddenly discovered that the expansion of the alloy in the diamond seemed to be much smaller than the previous one.

In some big steel-producing countries, such as our country, the price of liquid nitrogen is often only 600 yuan per ton, which is not as expensive as mineral water sold in supermarkets.

In the end, after melting more than one meter of diamonds, it sank inside the huge diamond.

And the purity of this diamond is very high.

In this way, its physical properties will gradually return to the values ​​under normal pressure, thus losing the ability to resist high temperatures, and finally it can only be melted away.

Because the electrons moving around the nucleus are negatively charged, the same charges repel each other. After the pressure decreases, the nickel and iron atoms gradually return to the size under normal pressure.

Yang Dongsheng roughly estimated that the nickel-iron alloy had expanded by about 50%.

How can this happen?The fracture should be caused by too fast temperature drop and expansion. What is the cause of the expansion...

Yang Dongsheng put the expanded nickel-iron alloy on the surface of the diamond. Like other nickel-iron alloys, it melted into the surrounding "ocean".

After the alloy was sprayed out, although the surrounding temperature dropped, it melted instead.

Enough to throw the rest of the world down for generations!
In addition to superhardness, super high temperature resistance, and superconductivity, according to the data, neutron stars also have superfluidity and supermagnetism...

The temperature here is estimated to be above 3000 degrees, which has long exceeded the melting point of most metals and alloys, including nickel-iron alloys.

The ice layer immediately gasified, and then the entire alloy quickly sank like a piece of red-hot carbon placed on lard.

Although the boiling point of diamond is only 4827 degrees, it is much lower than the temperature of that alloy at this time.

He intercepted a section of nickel-iron alloy with a length of half a meter, a thickness of five centimeters, and a width of ten centimeters from the core of the earth, and put it in the Wannian Glacier in Greenland.

What's even more strange is that it actually swelled, from the original "table legs" to "corn cobs".

Coupled with the fact that it is located at a depth of more than 1100 kilometers underground, and there is huge pressure around it, it is even more secure.

But to be honest, except for controllable nuclear fusion, the high temperature of hundreds of millions of degrees is basically not used on the earth.

Yang Dongsheng clutched his forehead and thought hard for a long time, but he couldn't come up with a solution.

This time, it can still be seen that it is a cuboid, but some parts seem to be swollen, and the nickel-iron alloy has only swelled by more than 10%.

After waiting for a while, seeing that the inside of the diamond had completely calmed down, it even gradually showed signs of solidification, and the alloy did not expand anymore.

Yang Dongsheng moved the piece of nickel-iron alloy to the surface of the diamond at a depth of 2800 kilometers last time, and then stared at it without blinking.

1 minute, 2 minutes, 5 minutes...
