Abstract

Tensile tests and static fracture toughness tests were carried out on variously heat-treated type IV gold alloys. The effects of microstructures on tensile characteristics and static fracture toughness were discussed. The tensile strength of type IV gold alloy increases with increasing solutionizing temperature. Moreover, the tensile strength of type IV gold alloy increases with increasing ageing time when the solutionizing temperature is 1023 K. While the elongation of type IV gold alloy decreases with increasing solutionizing temperature. Static fracture toughness of type IV gold alloy increases with increasing solutionizing temperature. Static fracture toughness of type IV gold alloy of aged for 0.3 ks is the greatest, and that of aged for 1.8 ks is the smallest when the solutionizing temperature is 1023 K.
