Stress corrosion cracking (SCC and mechanical property data were taken on Mulberry specimens heat treated at preselected temperatures to obtain representative microstructures. Results show that, in general, the higher the temperature of the heat treatment is, the more α-uranium is produced in the microstructure, the higher the mechanical strength is, and the more resistant the material is to SCC. Mechanisms are presented to explain the effect of the microstructure on both the initiation and propagation of stress corrosion cracks.
