Procedures are presented which permit prediction of the strength remaining in hardened metallic materials after complex temperature and stress exposures. These are based primarily on application of rate-process theory in the form of the time-temperature parameter T(C + log t) to the overaging or annealing reaction. The approach is reviewed in detail for the aluminum alloy 7075-T6. Generalized curves covering strength in tension, compression, bearing, and shear at several test temperatures after a wide variety of unstressed and stressed thermal exposure conditions were developed for this alloy. Application of the same basic approaches to other alloys is also discussed.
