Abstract

The present work aims to investigate the effect of strain reversal during high pressure torsion on the evolution of microstructure, texture and hardness properties of two different materials with different dynamic recovery behavior, namely, high purity Aluminum (>99%, designated as 2N-Al) and Aluminum-Magnesium (Al-2.5%Mg) alloy. For this purpose, 2N-Al and Al-2.5%Mg were subjected to monotonically (CW) and strain reversal (CW-CCW) deformation by High Pressure Torsion (HPT). The samples were subjected to a series of rotations in monotonically and strain reversal deformation with same equivalent strains of 1, 4, 12, 24 and 60 under an applied load of 6 GPa and with 1 rpm under quasi-constrained conditions.
