Abstract

The elastic-plastic fracture toughness J_IC of two titanium-zirconium-molybdenum (TZM) alloys with different kinds of grain boundary particles was estimated at elevated temperatures using the convenient J_IC test method with a suitable depth of side-groove for determining the J_IC at the maximum load point. It was found that the convenient J_IC test method can be successfully applied to evaluate high temperature fracture toughness at least up to 1200 °C. The J_IC values at temperatures ranged from 800 °C to 1200 °C were almost constant regardless of temperature, while the J_IC values of the TZM with carbide particles were higher than those of the TZM with oxide particles. The TZM with different forging rates showed similar J_IC values, which suggested the effect of forging rate would be not significant at high temperatures.
