Title: Facture behavior of Al-Fe-V-Si composite reinforced with SiC particles at different tensile temperatures
Abstract: SiCP/Al-11.7Fe-1.15V-2.4Si composite was prepared by spray deposition and densified by hot pressing,and then were rolled into sheets.The microstructures,fracture properties and fractographies of the composite at different tensile temperatures were investigated.The results show that the uniform distribution of the SiC particles with their longitudinal direction parallel to the rolling direction is achieved by rolling after hot pressing,which contributes to the elevation of the mechanical properties of the composite.Fracture properties and fractographies of the composite are affected by the tensile temperature and distribution and orientation of SiC particles.The bonding between SiC particles and the matrix becomes weak,and the breakable particles reduce as the tensile temperature;the debonding of SiC/Al becomes the dominant fracture mechanism,the plasticity of the composite decreases as the tensile temperature increases,which is different from the matrix alloy.
