STRENGTH PREDICTION AFTER SEVERE AND COMPLEX THERMAL HISTORIES 600412
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.
