Abstract

TZM alloys used as isothermal forging die at high temperature were prepared by a new powder doping process combined with the rational design of sintering technique and hot working technology. In this paper, tensile properties of TZM alloys at room temperature and properties such as tensile properties, fracture toughness and stress rupture at elevated temperatures were investigated. The results show that the mechanical properties at room temperature were excellent in accord with the ASTM B386-03 (2011) standard. At the temperature of 1100 °C, the tensile and yield strength were 552 and 514 Mpa respectively, and the endurance life is 250 h under the load stress of 160 Mpa, the TZM alloys can be used as isothermal forging die material at temperature of 1100 °C or above.

Keywords
