The formed product is compact and uniform in texture, and any complicated members can be directly manufactured without being secondarily processed.

Description

technical field [0001] The invention belongs to the molding technology of metal-based composite materials, and in particular relates to a molding device and method of aluminum-based silicon carbide particle-reinforced composite materials and components thereof. Background technique [0002] Among metal matrix composites, aluminum-based silicon carbide particle-reinforced composites have the characteristics of high thermal conductivity, low density, thermal expansion coefficient matching the chip, high hardness and high flexural strength, etc., and are widely used in electronic packaging and precision Manufacture of key components of the instrument. At present, the molding methods of aluminum-based silicon carbide particle-reinforced composite materials mainly include four methods: powder metallurgy, stirring casting, pressure casting and spray deposition. The powder metallurgy method has the disadvantages of cumbersome process, high cost, limited product shape, and uneven i...
