Introduction of aluminum silicon carbide

2022-01-10

Aluminum silicon carbide is one of the most common and important materials in metal matrix composites. Aluminum silicon carbide is a kind of particle reinforced metal matrix composite material, using Al alloy as the matrix, according to the design requirements, in a certain form, proportion and distribution state, with SiC particles as reinforcement, constitute a clear interface of multi-group phase composite material, both a single metal does not have the comprehensive superior performance.
Aluminum silicon carbide was developed earlier and the theoretical description is relatively perfect. Its main classification can be divided into high-body aluminum silicon carbide (SiC volume ratio 55%-75%), medium-body aluminum silicon carbide (SiC volume ratio 35%-55%) and low-body aluminum silicon carbide (SiC volume ratio 5%-35%) according to the volume content of silicon carbide.

Introduction of Aluminum Silicon Carbide Preparation Technology

According to the structural design requirements, making the reinforcement material SiC evenly distributed in the matrix is also one of the key technologies in the manufacture of aluminum silicon carbide materials. Especially in the low volume aluminum silicon carbide stirring method, vacuum pressure infiltration method, powder metallurgy method, the agglomeration of SiC particles, and the uniform distribution of SiC particles of different sizes is a difficult point.
