Recovery and recrystallization behavior of aluminum processed by extrusion-preceded equal channel angular pressing

Abstract

High-purity aluminum was severely plastically deformed by miniaturized extrusion-preceded ECAP as well as by cold rolling. Isochronal and isothermal annealing was performed to investigate the recovery and recrystallization behavior by measuring the development of Vickers microhardness and electrical resistivity.

Both processes were found to take place which was verified by TEM and EBSD observations.
