Chapter 152 Single Crystal Alloys (Subscription Request)
Chen Jue saw that the old technical consultant had been staring at the iron cube in his hand and kept looking at it. He knew that this man was an expert, so he rolled the iron cube along the table like a dice and rolled it in front of him: "Old sir, please take a look!"

"Thank...thank you!"

Upon seeing this, the other party's expression immediately changed. He grabbed the iron cube and held it in his hand to examine it carefully. At the same time, he picked up the pen from his chest pocket, tilted his ear, and tapped the cube lightly with the metal cap of the pen.

"There's really no sound at all! Oh my God!"

The old technical consultant tapped the pen cap several times, but didn't hear any tapping sound. His eyes almost became as big as light bulbs.

"Engineer Wu, what's wrong? Is there something wrong with the material of this block?" Seeing the startled look of the elderly technical consultant, Xiang Qingshan, who was sitting on the main seat, couldn't help but look in the direction of the voice.

Engineer Wu swallowed his saliva and said, "Director Xiang! This is not an ordinary metal material. This... This is a whole piece of single crystal alloy!"

"What did you say?"

"Single crystal alloy?!"

"Let us compare the product parameters with a single crystal alloy in terms of performance? Shit... shit!"

As soon as these words were spoken, the entire conference room exploded.

Especially the vice president in charge of sales and Xiang Qingqing who looked confident of winning, both turned green.

As senior executives of Tsingshan Holdings, even if they don't understand technology, they understand what "single crystal alloy" means.

The so-called "single crystal" refers to a solid state in which the molecules (atoms or ions) contained in the solid crystalline material are arranged regularly and periodically in three-dimensional space.

For example, common snowflakes and small particles of salt are very common single crystal substances formed in nature, and they are nothing big in the eyes of ordinary people.

But once 'single crystal' and 'alloy' are combined using a certain process, it will create a miracle in human metal materials science!
Ordinary alloys such as stainless steel produced by Tsingshan Holdings are "polycrystalline" solid crystalline materials.

Polycrystalline materials are composed of multiple small crystals, which results in certain gaps and impurities inside the material at a microscopic level. Once they encounter high temperatures and vibrations, they are prone to melt or break, losing their original solid form.

But single crystal alloys are different!
It is cast from a whole grain and has excellent high temperature strength, good oxidation resistance and hot corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties.

Take the turbine blade material of the aircraft engine, which is the most widely used in human technology today. It must be made of "single crystal blades" made of nickel-iron alloy containing rhenium.

Because this 'single crystal blade' can work for a long time under harsh working conditions above 600°C and certain stress without deformation.

Even the hot end components of gas turbine engines used on aircraft carriers and warships are basically made of single crystal alloys.

To put it simply, 'polycrystal' is like a Rubik's Cube with nine grids. It is easy to disassemble once you get the hang of it. You can hear the noise inside the Rubik's Cube by shaking or tapping it.

On the other hand, the 'single crystal' is like a solid dice, and it hardly makes any sound when shaken or knocked.

Because its internal molecules are arranged so tightly that no matter how external vibrations stimulate it, it will remain motionless.

This is also why after Engineer Wu got the iron cube from Chen Jue, he used a pen to tap it to listen to the sound.

He was using the echo of knocking on metal to detect the characteristics of the material. "I didn't expect that Mr. Chen's material was actually a single crystal alloy! I wonder which generation of technology it is? If it is the second or third generation of technology, then there is no need to test any material performance parameters in the future. On behalf of Qingshan Holdings, I admit defeat directly." Xiang Qingshan laughed, acting very bachelor.

"Mr. Xiang, you are too polite. This single crystal alloy was found by chance in our Cube Technology Laboratory. It can barely be considered third generation in terms of technology." Upon seeing this, Chen Jue spread his hands and started talking nonsense. By the way, he asked Tie Laoliu to take the iron block back from the reluctant Engineer Wu.

You should know that the casting of single crystal alloys is usually divided into three generations according to the type of process, as well as two manufacturing process routes: "seed crystal method" and "crystal selection method".

The first generation of single crystal alloys is called 'Ni-based high temperature', the second generation is 'Directed Grain Boundary', and the third generation is 'Re-containing Single Crystal'.

With the improvement of technology, the comprehensive ability of this type of alloy to withstand high temperatures will be greatly improved.

Take the F22 engine installed on the F119 Raptor fighter jet by the Americans, as well as the domestic WS-15 series, both of which basically use the third-generation single-crystal blades.

"It's actually the third generation? Then it's not unfair that we lost." Xiang Qingshan sighed when he heard that.

After learning that the material Chen Jue took out to deal with the gambling was actually a third-generation single crystal alloy, the expressions of the Qingshan Holdings executives present became complicated.

This isn't even a gamble, it's simply a dimensionality reduction attack!

In particular, Xiang Qingshan had been playing with stainless steel and nickel-iron alloy for half his life, but in the end he was taught a lesson by a young man.

After all, no matter how large the output value of Tsingshan Holdings is or how many nickel mines it controls, in the end it is just a leading company engaged in civilian stainless steel.

Even if Xiang Qingshan sharpened his head, he couldn't get the third-generation single crystal alloy, a cutting-edge metal material comparable to the strategic level!

Because materials of this level are mostly controlled in a laboratory or a confidential factory.

Even if they appear on the market, they are usually only shown as models at some large airport or ship exhibition, where people can only take a glimpse of them and touch even the dust on them.

There are single crystal alloys circulating in the civilian field, and most of them are the second-generation "nickel-based single crystal high-temperature alloys" with the brand name DD406.

After all, DD406 is independently developed in China, and the formula is publicly authorized in the stainless steel industry, so you can get the production process by spending money.

Including Tsingshan Holdings, which already has the DD406 production line in operation.

As for the piece of BUG material in Chen Jue's hand, which was cut from the MC [iron block], if you look closely, this thing can be considered a super single crystal among elemental iron.

Why is it described as a super single crystal?
Because of the smelting under the MC furnace rule system, all tangible impurities in the iron ore are removed, and even the gaps between the iron elements in the [iron block] are compressed to a level that is difficult to imagine with human technology.

If you want to compete with this BUG-level material in terms of parameters, you probably have to find a collapsing neutron star in the universe.

By utilizing the high gravity and high density of neutron stars and digging out some solid iron shell on its surface, we might be able to compete with MC [Iron Block].
