Description
Technical Field
The invention relates to the technical field of amorphous alloy thin-wall rod piece manufacturing, in particular to thin-wall rod piece manufacturing equipment and a thin-wall rod piece manufacturing method.
Background
By thin-walled rod, it is meant that the length L of a geometric feature in a direction is much greater than the characteristic dimension d of a cross-section perpendicular to that direction (i.e., the largest dimension in the cross-section, such as diameter, height, width, etc.), while the maximum thickness t in the cross-section is less than or equal to the characteristic dimension d in the cross-section. The application of the thin-wall rod piece is very wide, and with the promotion of a deep space exploration plan, the development of the technology for manufacturing the thin-wall rod piece in the space in situ is more urgent. The metal material has an irreplaceable effect in the field of aerospace, and the existing manufacturing and processing method (particularly metal material additive manufacturing) which uses the metal material as a raw material mostly adopts metal powder or metal molten liquid as the raw material, so that the problem of powder or liquid drop splashing can be caused in the space weightless environment. In addition, because the melting temperature of the metal material is high, the problems of serious heat accumulation and difficult heat dissipation exist in the space high-vacuum microgravity environment during molten state processing.
Amorphous alloys, also known as metallic glasses, are solid alloys with long-range disordered structures formed by the out-of-order arrangement of atoms during the rapid solidification process, and have no defects such as grain boundaries, dislocations, etc. in crystalline alloys. This gives amorphous alloys many unique properties such as excellent soft magnetic properties, corrosion resistance, wear resistance, high strength, hardness and toughness, high electrical resistivity and electromechanical coupling properties, etc., and thermoplasticity in the supercooled liquid temperature region of about two-thirds of the melting temperature. Amorphous alloys are various in kind, and from the viewpoint of composition materials, they can be classified into various amorphous alloy systems such as Pd-based (palladium-based), Mg-based (magnesium-based), rare earth-based, Ti-based (titanium-based), Fe-based (iron-based), Cu-based (copper-based), Ni-based (nickel-based), Zr-based (zirconium-based), and Al-based (aluminum-based). From the aspect of morphology, the amorphous alloy can be classified into bulk amorphous (thickness >1mm), amorphous ribbon, amorphous wire, amorphous powder, amorphous plating, and the like.
The amorphous alloy strip is used as a raw material for producing the thin-wall rod piece, and is processed in the thermoplastic temperature range of the amorphous alloy strip, so that powder and liquid drops in the manufacturing process can be prevented from splashing in the space weightless environment, and the heat accumulation is reduced. However, the apparatus for manufacturing thin-walled rods from amorphous alloy ribbon as a raw material is currently lacking in the market.
