Abstract：By means of chemical composition,macroscopic and microscopic fracture and metallographic microstructure analysis,fracture failure analysis of high specific gravity 93WNiFe tungsten alloy explosive components were studied.The results show that the chemical composition of the alloy is normal,but the microstructure and density are different.The fundamental cause of failure and fracture of explosive parts is caused by improper heat treatment process in the process of materials preparation.The heat treatment process and the inspection scheme of explosive parts should be strictly controlled.
