摘要：
An Al-Li-Cu (AA2091) alloy was subjected to equal channel angular pressing (ECAP) at 210 degrees C following route B-C to a maximum strain of epsilon=8.64. A considerable particle age hardening anticipation with respect to an isochronal aging treatment was documented. At epsilon=6.48, the alloy reached a peak hardness level, while at epsilon=8.64, the alloy overaged and partial dissolution of the two most abundant hardening particles, T-1 plates and S' laths, was induced by ECAP/B-C.
