Abstract

The invention provides a forming device of an amorphous alloy near-net-shape casting. The forming device comprises a vacuum chamber, an infrared thermometer, a water cooling system, a copper mold, a pouring cup, a crucible and an induction coil. The invention further provides a preparation method of the amorphous alloy near-net-shape casting combining casting and suction casting. The preparation method comprises the steps that S1, alloy raw materials are weighed; S2, the alloy raw materials are cleaned and dried; S3, the vacuum chamber is vacuumized; S4, the amorphous alloy near-net-shape casting is prepared; and S5, the amorphous alloy near-net-shape casting is subjected to aftertreatment. According to the forming device and the preparation method, rapid forming of large-size amorphous alloy is achieved, and the problems that a traditional casting method is poor in mold filling capacity, and the large-size amorphous alloy cannot be prepared through a traditional suction casting methodare solved through a casting-suction casting method.

Description

technical field [0001] The invention belongs to the field of near-network preparation of amorphous alloys, and is particularly suitable for producing near-network parts of amorphous alloys with different sizes and shapes. Background technique [0002] Amorphous alloys have many excellent properties due to their unique structure, such as high strength, high hardness, high corrosion resistance, excellent magnetic properties, and superplasticity at a certain temperature. Amorphous alloys have an extremely fast cooling rate during shape casting, which greatly limits the size and shape of amorphous parts produced. The research and development of bulk amorphous alloys has broken through the size limit of thin ribbon amorphous alloys and has great application prospects. In recent years, the copper mold casting method is the most commonly used method for preparing bulk amorphous alloys. The casting methods mainly include casting method, suction casting method, squeeze casting met...
