Abstract
In-situ tensile tests are conducted to investigate the fracture behaviors of particulate-reinforced tungsten alloy by means of S-570 SEM system. The processes of the crack initiation, propagation and connection of tungsten alloys under quasi-static loadings are obtained. Metallographic analysis is adopted to study the cross section of the specimens used in the tensile tests. The relation between the patterns of the cross section and the macro mechanical properties is discussed. It is found that the fracture patterns exert an important influence on the macro mechanical characteristics of tungsten alloys, and in order to improve the macro mechanical properties, the tungsten particles with high strength are needed to bear the main loadings.
