Abstract

Preliminary thermomechanical treatments (PTMTs) for age-hardening aluminum alloys have been proposed to improve thermomechanical fatigue (TMF) resistance. Preferential orientation of precipitates perpendicular to the loading direction, achieved in advance by applying an out-of-phase PTMT with small temperature and strain ranges, can effectively prolong in-phase TMF life. This has been shown to correlate with the degree of preferential orientation due to mechanical anisotropy introduced during PTMTs.
