The more you think you know something or technology, the easier it is to think that you see something that you don't understand.

Kobayashi well travelers, self-proclaimed Nippon Polytechnic University, far surpassed Zhongyun University in the study of powder metallurgy technology.

So after seeing Ye Qing's pigment-like formula, it feels very funny.

High purity alcohol has volatile properties and can theoretically act as a humidifier. However, chemical reactions may occur in various metals and non-metallic powders, and internal alcohol may not volatilize completely due to the compression of embryos by hydraulic presses and increased powder density.

To solve this problem, embryos need to be placed on hold for long periods of time to allow alcohol to be completely volatile.

This wastes time and natural placement. After the embryo dries, slight deformation may occur, increasing the failure rate of the product.

This technology has long been eliminated on their side and converted into a specialized humidifier.

And the mix, only a backward ball grinder in this lab, and now a three-dimensional motion mixer, is the standard instrument in a top-notch lab.

It's too bad to throw up!

Kobayashi had the feeling of falling behind when he went to visit the university lab 30 years ago.

Ye Qing turned a blind eye to the laughter and ridicule of the Nippon Polytechnic University, mixed the five main powders at will, and then put them into a circular ring mold of different specifications, and diecast them into five different sizes with a hydraulic press.

The smallest round accessory, only the size of the lid, the biggest is similar to the bracelet.

If you measure their diameters, you'll see these rings from small to large, and the outer diameter of each ring is slightly larger than the one above.

“To make the Olympic ring?” Tanaka laughed badly: “The 2020 Olympic Games will be held in our country, and it will be said that the opening ceremony [the new national arena], the mechanical automation system inside, is still being designed by our school. ”

An industrial microscope used to observe the micro-well structure of the surface of the material was adjusted to the focal length by Ye Qing. Then, by means of the microscope, Ye Qing used a thousand decimal feet to carefully measure the size of each circular embryo, while using a carving knife, carefully at the edge of each embryo, engraved a semi-arcled concave surface similar to the gear.

After all engraving, Ye Qing accurately combined the five ring sets and recast them with a hydraulic press.

Those semi-arcled concave surfaces, after 500 tons of pressure cast by the hydraulic press, amazingly fused together.

No time was given to them. The embryos were combined and sent directly to the preheated vacuum sintering furnace by Ye Qing.

Nobody spoke on the side of Zhongyun University, and they were all nervously watching the sintering furnace temperature rise a little bit.

Ye Qing looked at the watch on his left hand and said calmly: “Wait another 12 minutes. ”

“Do you want me to help you with the timing?” Kobayashi showcased similarly, raised his left hand, illuminated a silver-white dial, a watch with a matte black metal strap, swayed: ”“ Seiko San asked the mechanical watch, with chronograph function, the error during daylight travel was controlled within 0.5 seconds. ”

“Eh…”

Ye Qing dragged the sleeve of the clothes and covered the piece on his hand. There are only a few pieces of the Baida Emerald 2499 red gold collection in the world, some of which are hard to say: “No… used. ”

Some of the opposing atmospheres continued into the vacuum arc furnace and were re-injected with protective nitrogen, balancing internal and external atmospheric pressure before being broken by great tension.

“It will definitely break into glass.” Kobayashi muttered in Tanaka's ears without any fear that they would be turned over.

Ye Qing smiled, wearing insulated gloves, with special pliers, clamped a flaming red from inside, some like a jade perfect disc.

The flaming disk is like a magnet that instantly attracts everyone's attention.

In the powder metallurgy lab, a sound of inhalation sounded.

“Not broken?” Professor Kobayashi rubbed his eyes and was surprised how possible.

When the object is heating, because of the heat transfer of the material, if there are cracks on the object, they become very visible black gaps. But the flaming disk in front of you is entirely one.

Fire red disk, little by little to remove excess heat.

Green, first appeared on the outermost periphery of the disc. Under the heat of the surrounding glow, the outermost emerald green became unusually permeable, flashing like a jade.

Then the second flame faded red, silver-white metal profile, allowing Kobayashi's eyeballs to become bigger and bigger as inflation.

Then the third purple, then the fourth white, the fifth transparent...

Green, silver, purple, white, transparent. Five different colors, staggered and natural.

Silver and white are metallic materials, while the remaining three are non-metallic materials.

Sintering between different metals and metals is already a huge piece of high-end technology. Ye Qing is holding five different colors, different kinds of sintering.

Laboratory lights, just give it a blurry five-color glow. As the last flame fades red, this beautiful disc appears to be alive, with life flowing in it.

“Impossible!” Just this afternoon, Tanaka, who showed two metal-sintered classmates, jumped up, not only breathing, but even thinking was stifled.

No gaps, totally natural.

“The melting point between the metal zinc and the quartz is 1150 degrees short, trying to sinter the quartz into a clear color, the melting point is only 420 degrees of metal zinc, which has long melted into a beach of waste. ”

“It's not science. ”

“That's pure zinc, but don't you know that the most common way to use zinc is to incorporate it into other metals and turn it into an alloy? ”

“I don't believe you, then tell me. Even zinc alloys, how can they be perfectly combined with quartz? ”

Not so much. Why, until the five-color disc cools down, Ye Qing handed it directly to the University of Science and Technology.

They put the five-color disk under an industrial microscope without dying to look at it with the most pungent gaze, still unable to find any cracks in it.

On the other hand, Zhongyun University is caught in the delight of tasting Pantaoyuan Immortal Fruit.

The hatred on the Japanese Polytechnic University's side could not get into the five-color disc, peeking into the mysterious expression of the atomic structure inside, making them refresh from the foot plate to the heavenly lid.

Is it better than that?

Sintering five materials, how many times higher than sintering two materials?

This is not yet the difficulty between metal and non-metal. It is not at all at an altitude, and the Himalayas are coming and cannot keep up the gap.

“Enough is enough.” Freshman Yan Tianjie walked in front of Tanaka as a winner.

“Hey, loser, you should keep your promise and apologize to us. ”
