A forming device and preparation method of an amorphous alloy near-net-shape casting

Abstract

The invention provides a molding device for near-net-type amorphous alloy castings, which includes a vacuum chamber, an infrared thermometer, a water cooling system, a copper mold, a sprue cup, a crucible, and an induction coil; the invention also provides a A method for preparing an amorphous alloy near-net casting combining casting-suction casting, comprising step S1: weighing the alloy raw material; step S2: cleaning and drying the alloy raw material; step S3: vacuumizing the vacuum chamber; step S4: preparing Amorphous alloy near-net-shape casting; step S5: post-processing the amorphous alloy near-net-shape casting. The invention realizes rapid prototyping of large-volume amorphous alloys, and solves the problem of poor mold filling ability of traditional casting methods and the inability to prepare large-volume amorphous alloys by using the casting-suction casting method.

Description

A kind of forming device and preparation method of amorphous alloy near-net-shape casting technical field The invention belongs to the field of near-net-shape preparation of amorphous alloys, and is particularly suitable for producing amorphous alloys of different sizes and shapes. Gold near-net parts. Background technique Amorphous alloys have many excellent properties due to their unique structure, such as high strength, high hardness, high corrosion resistance properties, excellent magnetic properties, and superplasticity at a certain temperature. Amorphous alloys have extremely rapid cooling during shape casting The speed of cooling, therefore, greatly limits the size and shape of the production of amorphous parts. The research and development of bulk amorphous alloys has broken through the thin The size limitation of ribbon-shaped amorphous alloys has huge application prospects. In recent years, the copper mold casting method has been used to prepare bulk amo...
