Abstract

An Al-3% Mg alloy was processed by Equal Channel Angular Pressing (ECAP) for 8 passes in route BC thereby reducing the grain size of the annealed sample from ∼400 μm to ∼300 nm. The as-pressed ultrafine-grained material was examined using depth-sensing indentation tests over different length scales with the overall objective of identifying the different deformation processes taking place in the bulk submicrometer crystalline material. At small indentation sizes with indentation depths of
