Abstract
In this study, 93W–5Ni–2Fe tungsten heavy alloy prepared by powder metallurgy method were tested at 1000, 1100, 1200, 1300 and 1400 °C respectively for investigating high temperature mechanical properties. Fracture analysis was carried out by scanning electron microscope and then developing principles of fracture mechanism obtained. The results showed that as the elevating temperature in the range of 1000–1400 °C, mechanical properties of 93W–5Ni–2Fe alloy, such as tensile strength, elongation, reduction of area and Young’s module were dramatically getting worse. Material becoming brittle, transgranular fracture hardly found, binder phase tear and interfacial fracture between tungsten grain and binder phases are domestic fracture mode.
