Effect of ECAP on Mechanical Properties of an AA2014 Alloy

摘要：

An AA2014 alloy was subjected to equal channel angular pressing in quenched condition up to fixed true strains of ~1, ~2 at a temperature of 170° C followed by artificial aging at the similar temperature. ECAP provides accumulation of a high dislocation density after a true strain of ~1 and the formation of subgrain structure and separate chains of nanoscale grains after a true strain of ~2. Yield stress (460 MPa) of the AA2014 alloy after 1 and 2 passes was the same. In contrast, increasing strain from ~1 to ~2 leads to three-fold increase in ductility.
