Abstract

The invention relates to a device and method for continuous block metal glass shaping, belonging to the technical field of metal material preparation. A heat insulating ring is arranged between a graphite casting mould and a water cooling copper mould which are arranged in a first vacuum chamber, an air cooler is arranged in a second vacuum chamber, and a traction rod enters the graphite casting mould and horizontally moves by a traction device. The method uses the graphite casting mould and the water cooling copper mould for primary main cooling and the air cooling mode for secondary auxiliary cooling, and the two vacuum chambers have a certain air-pressure difference. The device and the method have a high cooling speed, satisfy the requirements of the amorphous phase change of the blockmetal glass material. The shaping pressure of a metal melting body can be easily controlled, and the good shaping performance of the metal melting body is ensured by adjusting the pressure in the vacuum chambers. The metal passes through the graphite casting mould in a liquid state and is solidified in the water cooling copper mould, and the casting graphite casting mould has long service. The composite casting mould and the traction device have exchangeability to be convenient for realizing the continuous shaping of rod wires, boards, pipes and abnormal-shaped materials of different section sizes.

Description

technical field

[0001] The invention relates to a device and method for continuous molding of bulk metallic glass, which belongs to the technical field of metal material preparation, and in particular relates to the continuous preparation technology of bulk metallic glass and non-equilibrium solidified materials. Background technique

[0002] Bulk metallic glass is an amorphous material, which has higher thermal stability than ordinary amorphous alloys. The alloy melt does not crystallize and solidify even at a slow cooling rate of 0.1 to hundreds of K / s. The amorphous structure of the phase is frozen to a solid state, and an amorphous single-phase bulk material with a three-dimensional size of more than a millimeter can be obtained by casting. Compared with crystalline metal materials, bulk metallic glasses have more excellent mechanical, physical, chemical properties and precision molding characteristics, and show good application prospects in aerospace devices, precision ...
