摘要：

The research is carried out about the microstructure, mechanical properties, deformation and fracture feature of 93 W alloy deformed by hydrostatic extrusion. The result shows that the strength of tungsten alloy increases with the increase of the deformation amount, the elongation of tungsten alloy decreases with the increase of the deformation amount; The deformation initiates from binder phase. The deformation is typical two-phase harmonious deformation, the crack generate from the W-W interface; The ratio of W particle cleavage in fracture surface of deformed tungsten alloy is greater than that of undeformed.
