Chapter 152: Single Crystal Alloy (Subscription Requested)

Chen Jue noticed the old technical advisor staring intently at the iron cube in his hand, knowing this man was an expert. He casually rolled the iron cube across the table like a die towards the advisor: "Old sir, please take a look!"

"Thank… Thank you!"

Upon seeing this, the advisor's expression immediately changed. He picked up the iron cube, carefully feeling and examining it. At the same time, he took out the steel pen from his chest pocket, tilted his ear, and gently tapped the cube with the metal cap of the pen.

"There's really no sound at all! Heavens!"

The old technical advisor tapped it several times with the pen cap, but couldn't hear even the slightest sound of tapping. His eyes widened as if they were light bulbs.

"Engineer Wu, what's wrong? Is there a problem with this cube's material?" Seeing the elderly technical advisor's surprised reaction, Xiang Qingshan, sitting in the main seat, couldn't help but ask.

Engineer Wu swallowed: "Chairman Xiang! This isn't ordinary metal material, this… this is a whole piece of single crystal alloy!"

"What did you say?"

"Single crystal alloy?!"

"Asking us to compare product parameters with a single crystal alloy? Holy… crap!"

As soon as these words came out, the entire conference room erupted.

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

As high-level executives of Qingshan Holdings, even if they didn't understand technology, they knew what 'single crystal alloy' meant.

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

For example, common snowflakes and small grains of salt are very common single crystal substances formed in nature, and ordinary people don't think much of them.

However, once 'single crystal' and 'alloy' are combined using a specific process, it will unleash a miracle in human metal material science!

Ordinary alloys such as stainless steel produced by Qingshan Holdings belong to 'polycrystals' among solid crystalline substances.

Polycrystals are composed of multiple small crystal grains stacked together. As a result, the material itself has certain gaps and impurities at the microscopic level. Once exposed to high temperatures and vibrations, it is easy to melt or break, losing its original solid form.

But single crystal alloys are different!

It is cast from an entire crystal grain and has excellent high-temperature strength, good oxidation and hot corrosion resistance, and good fatigue performance and fracture toughness.

Take the turbine blade material of aero engines, which is currently the most widely used in human technology, it must be made of 'single crystal blades' made of rhenium-containing nickel-iron alloy.

Because this 'single crystal blade' can work for a long time under harsh conditions exceeding 600°C and under 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 that is easily disassembled after you get started. Shaking or tapping it will make sounds inside the cube.

On the other hand, 'single crystal' is like a solid die. It is difficult to make a sound no matter how you shake or tap it.

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

This is why Engineer Wu tapped the iron cube in Chen Jue's hand with a steel pen to listen for the sound.

He was using the echo of tapping the metal to test the properties of this material.

"I didn't expect that Mr. Chen's material would be a single crystal alloy! I wonder which generation of technology it is? If it is the second or third generation technology, there is no need to test any material performance parameters later. I will directly admit defeat on behalf of Qingshan Holdings." Xiang Qingshan laughed and acted very straightforward.

"Chairman Xiang is too polite. This single crystal alloy was accidentally obtained in our Square Technology laboratory. The technology can barely be considered third generation." Chen Jue spread his hands and started talking nonsense, and asked Tie Lao Liu to take back the iron block from Engineer Wu, who was reluctant to part with it.

It should be known that the casting of single crystal alloys is usually divided into 3 generations according to the type of technology, as well as two manufacturing process routes: 'seed crystal method' and 'crystal selection method'.

The first generation of single crystal alloys is called 'nickel-based superalloy', the second generation is 'directional grain boundary', and the third generation is 'rhenium-containing single crystal'.

With the improvement of technology, the comprehensive ability of these alloys to withstand high temperatures will be greatly improved.

Take the F119 engine installed on the F22 Raptor fighter jet of the Old America and the domestic WS-15 series, they basically use third-generation single crystal blades.

"It's actually the third generation? Then we didn't lose unjustly." Xiang Qingshan sighed.

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

This is not even a gamble, it's simply a dimensionality reduction attack!

In particular, Xiang Qingshan has been playing with stainless steel and nickel-iron alloys for half his life, but in the end, he was taught a lesson by a younger generation in person.

After all, no matter how large Qingshan Holdings' output value is and how much nickel ore it controls, in the end, it is just a leading enterprise playing with civilian stainless steel.

Xiang Qingshan couldn't get out the strategic-level cutting-edge metal material like the third-generation single crystal alloy even if he sharpened his head!

Because most of this level of material is controlled in the laboratory or a secret factory.

Even if it can appear on the market, it is usually only a glimpse in the form of a model at a large aviation station or ship exhibition, and people can't even touch a speck of dust.

Most of the single crystal alloys that are circulating in the civilian field are second-generation brands, DD406 'nickel-based single crystal superalloys'.

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

Including Qingshan Holdings, there is already a DD406 production line in operation.

As for the BUG material cut from the MC [Iron Block] in Chen Jue's hand, this thing can be regarded as a super single crystal in elemental iron if you look into it.

Why use super single crystal to describe it?

Because under the smelting of the MC furnace rule system, all the shaped impurities in the iron ore are removed, and even the gap between the iron elements in the [Iron Block] is compressed to a degree that human technology can hardly imagine.

If you want to do a parameter PK with this BUG-level material, you probably only need to find a collapsing neutron star in the universe.

Using the high gravity and high density characteristics of the neutron star, digging out a little solid iron element shell layer on its surface may still be able to compete with the MC [Iron Block].
