Abstract

Properties have been studied as a function of thorium concentration in the range 0 to 1000 ppm by weight. The solubility limit of thorium is below 30 ppm. Above this limit, excess thorium reacts to form second-phase particles. Thorium additions raise the recrystallization temperature and retard grain growth at high temperatures. The alloy without thorium fractured by grain boundary separation, while alloys doped with less than 550 ppm thorium failed mainly by transgranular fracture at 650 degree C. Impact properties were correlated with test temperature, grain size, and heat treatment.
