An Al–Li–Cu (AA2091) alloy was subjected to equal channel angular pressing (ECAP) at 210 °C following route BC to a maximum strain of ε = 8.64. A considerable particle age hardening anticipation with respect to an isochronal aging treatment was documented. At ε = 6.48, the alloy reached a peak hardness level, while at ε = 8.64, the alloy overaged and partial dissolution of the two most abundant hardening particles, T1 plates and S' laths, was induced by ECAP/BC.

Abstract
An Al–Li–Cu (AA2091) alloy was subjected to equal channel angular pressing (ECAP) at 210 °C following route BC to a maximum strain of ε = 8.64. A considerable particle age hardening anticipation with respect to an isochronal aging treatment was documented. At ε = 6.48, the alloy reached a peak hardness level, while at ε = 8.64, the alloy overaged and partial dissolution of the two most abundant hardening particles, T1 plates and S' laths, was induced by ECAP/BC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
