摘要：

B4C has a lower specific gravity than either Al or SiC (2.52 g/cm3 compared with 2.7 for Al and 3.2 for SiC). It has a similar thermal expansion coefficient, higher specific stiffness and strength as compared to SiC. The incorporation of B4C particulates into 7091 Al alloy can improve the tensile modulus, yield strength and tensile strength of the monolithic matrix alloy. However, the ductility and fracture toughness need to be improved through optimization of processing parameters. The fracture was primarily along the particle/matrix interface.
