摘要：
The development and recovery of damage in continuously cast aluminium alloy 6061 due to plastic deformation is investigated for different stress histories. The processes of Equal Channel Angular Extrusion and Equal Channel Angular Drawing are used to introduce damage into the specimen for a specified stress history. The amount of plastic deformation is determined by the angle between the two intersecting channels, while the stress history is varied by applying different back-pressures. The damage is related to the density, measured using Archimedes' principle.
