摘要：

Preliminary thermomechanical treatments (PTMTs) for age-hardening aluminuml 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, call effectively prolong in-phase TMF life. This has been shown to correlate with the degree of preferential orientation due mechanical anisotropy introduced during PTMTs. (c) 2008 Acta Materialia Inc. Published by Elsevier Ltd.
