【Abstract】 Elements distribution, microstructure and fracturegraphy of W Mo FGM are studied by electron probe microstructure analysis (EPMA) and scanning electron microscope (SEM). As a whole, W Mo FGM is dense, and elements distribution is gradually changed. The sections of rich W and rich Mo show brittle fracture, but fracturegraphy of interfaces has the characteristic of ductile fracture.更多还原
