The precipitates of densely distributed prior particle boundary mayembrittle the bonding boundaries among particles, reduce the plasticity and fracture alongtheir globular surfaces. An improvement on interfacial bonding strength, plasticity at hightemperature, as well as stress rupture life of the alloy may be made by broadening theinterstices between precipitated particles. Thus, the fracture mode is changed fromintergranular to transgranular.
