technical field

The invention relates to the technical field of manufacturing of amorphous alloy thin-walled rods, in particular to a thin-walled rod manufacturing equipment and method.

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 this 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 in the cross section. The application of thin-walled rods is very extensive. With the advancement of the deep space exploration program, the development of in-situ manufacturing of thin-walled rods in space is more and more urgent. Metal materials have an irreplaceable role in the aerospace field. The 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. Causes powder or droplet spattering problems. In addition, due to the high melting temperature of metal materials, molten state processing in the high vacuum and microgravity environment of space will have the problems of serious heat accumulation and difficult heat dissipation.

Amorphous alloys, also known as metallic glasses, are solid-state alloys with long-range disordered structures formed due to the inability of atoms to arrange in order during rapid cooling and solidification. 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. Two-thirds of the subcooled liquid temperature region is thermoplastic. There are many kinds of amorphous alloys. From the perspective of composition materials, they 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) Base), Ni-based (nickel-based), Zr-based (zirconium-based), Al-based (aluminum-based) and other amorphous alloy systems. From the morphological point of view, amorphous alloys can be divided into bulk amorphous (thickness>1mm), amorphous ribbon, amorphous wire, amorphous powder, amorphous coating, etc.

Using amorphous alloy strip as the raw material for the production of thin-walled rods, processing in the thermoplastic temperature range of the amorphous alloy strip 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 for manufacturing thin-walled rods from amorphous alloy strips on the market.
