technical field

Background technique

Thin-walled rod means that the length L of the geometric feature in a certain direction is much larger than the characteristic dimension d of the cross section perpendicular to the direction (that is, the largest dimension on the cross section, such as diameter, height, width, etc.), and the The maximum thickness t ≤ the characteristic dimension d on the cross section. The application of thin-walled rods is very extensive. With the advancement of the deep space exploration program, it is more and more urgent to develop the technology of in-situ manufacturing thin-walled rods in space. Metal materials play an irreplaceable role in the aerospace field. Existing manufacturing and processing methods using metal materials as raw materials (especially metal material additive manufacturing) mostly use metal powder or metal molten liquid as raw materials. In the weightless environment of space, it will Causes problems with powder or droplet splashing. In addition, due to the high melting temperature of metal materials, molten state processing will have serious heat accumulation and difficulty in heat dissipation in the high vacuum and microgravity environment of space.

Amorphous alloy, also known as metallic glass, is a solid alloy with a long-range disordered structure formed due to the lack of orderly arrangement of atoms during the rapid solidification process. There are no defects such as grain boundaries and dislocations in crystalline alloys. This makes amorphous alloys have many unique properties, such as excellent soft magnetic properties, corrosion resistance, wear resistance, high strength, hardness and toughness, high resistivity and electromechanical coupling properties, etc., and at about three melting temperatures Two-thirds of the subcooled liquid phase temperature region is thermoplastic. There are many kinds of amorphous alloys, which can be divided into Pd-based (palladium-based), Mg-based (magnesium-based), rare earth-based, Ti-based (titanium-based), Fe-based (iron-based), Cu-based (copper-based) from the perspective of composition materials. base), Ni base (nickel base), Zr base (zirconium base), Al base (aluminum base) and other amorphous alloy systems. From the point of view of morphology, amorphous alloys can be divided into bulk amorphous (thickness > 1mm), amorphous strip, amorphous wire, amorphous powder, amorphous coating, etc.

The amorphous alloy strip is used as the raw material for the production of thin-walled rods and processed in the thermoplastic temperature range of the amorphous alloy strip, which can avoid powder and droplet splashing in the manufacturing process in the weightless environment of space, and reduce heat accumulation at the same time. However, there is currently a lack of equipment on the market that uses amorphous alloy strips as raw materials to manufacture thin-walled rods.
