Document Type and Number:
WIPO Patent Application WO/2022/016609
Kind Code:
A1
Abstract:
A product preparation process, which is used to solve the existing technical problem of processing being extremely difficult when hard metals or hard alloys are used to produce products with high hardness. The method comprises: placing a hard metal rod or a hard alloy rod and an amorphous alloy rod in a preset cavity for mixing; heating the mixed material to the temperature range of a supercooled liquid phase zone of the amorphous alloy rod; making the amorphous alloy rod flow in a semi-solid state by means of applying pressure, and driving the hard metal rod or the hard alloy rod mixed with the amorphous alloy rod to deform together into the shape of the preset cavity; cooling the mixed material to obtain a composite material; placing the composite material into a product mold; injecting a liquid metal material into the mold, such that the liquid metal material is mixed with the composite material; applying a preset pressure to the mold and maintaining the pressure for a preset time, and then opening the mold to remove the product.
