Amorphous alloy (also known as liquid metal or metallic glass) is an advanced and high-performance material supported by China. Because of its excellent mechanical and physical and chemical properties (high strength, wear resistance, high elasticity, corrosion resistance, excellent biocompatibility, etc.), bulk amorphous alloys are used in the fields of IT, mechanical equipment, military weapons, aerospace, etc. have a broad vision of application.
However, the difficulty of forming is a world problem that restricts its actual scale application (yield rate, low forming efficiency), and the industrial production of centimeter-thick amorphous alloy products (non-laboratory test) is even more difficult.
China's leading amorphous alloy technology company: JSHD Amorphous Alloy Technology Corporation, after years of technological innovation and accumulation, has successfully achieved high yield, high efficiency, and industrialized mass production of centimeter-thick amorphous alloy products. This innovation will greatly broaden the practical application of bulk amorphous alloy products and break the previous embarrassment of limited application due to the small size of the product (thickness less than 5mm).
As a metal material, amorphous alloys have the characteristics of glass, metal, solid and liquid at the same time. Therefore, amorphous alloys have maintained many records of metal materials. for example:
.Amorphous alloy is the strongest metal material found so far, among which the strength of the strongest cobalt-based amorphous alloy reaches a record-breaking 6000MPa;
.Amorphous alloy is the strongest armor-piercing material found so far;
.Amorphous alloy is the most corrosion-resistant metal material, one of the most ideal micro- and nano-processing materials.
This new material with unique performance has developed into a fashionable material for today's aerospace, aviation and other high-tech and high-end watches, mobile phones, laptops and other fashion products.
Amorphous alloy also has a wide range of composition modulation, supercooled liquid zone (softening zone), genetic, memory, soft magnetic, large magnetic entropy and cold storage effect and other unique properties. Based on these advantages of amorphous alloys, the trend of industrialization of amorphous alloys is gradually increasing.
Although the industrialization of amorphous alloys in China started late, it has developed rapidly and is now at the forefront of the world. Even so, the thickness of amorphous alloy products that can be industrialized and mass-produced worldwide is generally less than 5 mm. Although scientists can successfully prepare centimeter-level amorphous alloys with different compositions in the laboratory, they are still unable to supply large-size amorphous alloy products in batches due to the backwardness of amorphous alloy industrialization technology, which severely limits the use of amorphous alloys. Applications in various industries.
In order to break this predicament, after years of technological innovation and optimization, JSHD produced centimeter-level amorphous alloy products for the first time. It broke the size limit barriers of amorphous alloys in industrial applications and greatly enriched the applications of amorphous alloys. Scenes.
While centimeter-level amorphous alloy products can be mass-produced industrially, we are also curious about the magic of this new amorphous alloy processing technology.
According to Dr. Zhang, CTO of JSHD, “The amorphous alloy forming technology invented by JSHD can achieve a finish and appearance close to the finished product through only one-step technical forming. The new technology has high forming efficiency and the formed amorphous alloy products have good performance. The maximum size of the formed amorphous alloy product is a breakthrough in the centimeter level.” Thanks to the innovation of new technology, the processing cost of the amorphous alloy products produced by JSHD has been lower than that of CNC machining. It is extremely high in terms of performance, dimensional accuracy, and complexity.
China's amorphous alloy development
When steel, aluminum alloy, and titanium alloy are prepared into amorphous materials, the performance changes greatly.
Soft magnetic, degradable, large elasticity, high strength and toughness, catalysis, thermoplasticity, corrosion resistance and abrasion resistance, etc. are the properties obtained after being made into amorphous alloys, which has opened up many paths for the application of amorphous alloys and formed a huge application Group, "The soft magnetic amorphous alloy is currently the most effective and most abundant material."
With regard to the use of this characteristic of amorphous alloys, in 2005, Chinese scientists studied a new metallurgical process in the extreme environment of the laboratory, allowing amorphous alloys to be blow-molded like glass and processed into more complex shapes by micro-nano processing. .
For example, the use of amorphous alloy die-casting wireless earphones can not only be precisely die-cast into complex shapes like plastic, but also can obtain higher strength and better sound effects.
In the key components of aerospace, high expectations are placed on the application of amorphous alloys. It is also the main research direction of many amorphous alloy technology companies in China, covering the research of flexible gears, mirror components and other components.
The elasticity of amorphous alloys is dozens of times higher than that of conventional metals. It is uniquely used for flexible gears. It can work normally even in harsh environmental conditions such as space, without the need to add lubricating oil after sand has entered. "China Amorphous Alloy Technology Corporation has developed this type of flexible gear, which has obvious advantages over traditional metal materials," said academician Wang Weihua.
Amorphous mirrors are another direction for China's amorphous alloy R&D team. This is a mirror installed on a space vehicle to image the ground. In the future, as space exploration deepens, it will have a wider range of applications. When the amorphous alloy is used in this equipment, it can meet the requirements of smooth and good reflectivity of the mirror surface, and significantly improve the resolution of imaging on the ground.
At present, the research on amorphous alloy mirrors in China has made progress, and the imaging effect in the laboratory is ideal. It is hoped that this research can be applied to lunar exploration projects in the future.
There are more applications for amorphous alloys. For example, high-strength, high-toughness amorphous alloys are candidates for the third-generation armor-piercing and armor-piercing projectiles. Amorphous alloys with high specific strength and high elastic limit are expected to be used in key components of aerospace vehicles. In addition to these defense applications, amorphous alloys also have application value in high-end manufacturing equipment such as high-speed and high-frequency motors for new energy vehicles, wireless charging devices for mobile phones and robots.
