Al/SiCp ceramic matrix composites thixoforming in pseudo-semi-solid state

A new forming method, the ceramic matrix composites thixoforming in pseudo-semi-solid state, was presented based on the powder metallurgy in combination with the semi-solid metal forming and the developing direction of the ceramic forming in the 21st century. The angle-frames were produced by the method with SiC_p as the matrix materials and 30Al as the plasticization phase. The results show that the component' microstructure with 6.43 GPa Hv and about 0.5% strain stress as well as about 300 MPa tensile strength is homogeneously formed. It will play a very important role in promoting the application of the ceramic matrix composites and high melt point materials in more fields.
