Description

Technical field

[0001] The invention belongs to the technical field of combustion synthesis preparation, and specifically relates to a thermite agent used for supergravity assisted combustion synthesis of copper-based composite materials. Background technique

[0002] Copper-based composite materials can give full play to the high electrical conductivity and high thermal conductivity of the matrix Cu, and the high strength, high hardness, and low thermal expansion coefficient of the reinforced phase or composite layer, and have excellent comprehensive physical and mechanical properties. According to the characteristics of composite, copper-based composite materials can be divided into three types: particle-reinforced, fiber-reinforced, and flat copper-clad. The particle reinforcement phase in the common particle reinforcement type includes W, Al 2 O 3 , SiC, AlN, diamond, etc. The fiber-reinforced phase in fiber-reinforced type includes C fiber, B fiber, SiC fiber, tungsten wire,...
