An Investigation of Strain‐Softening Phenomenon in Al–0.1% Mg Alloy during High‐Pressure Torsion Processing
Source abstract
Abstract
An Al–0.1% Mg alloy is processed by high‐pressure torsion (HPT) at room temperature. The Al–0.1% Mg alloy displays strain‐softening phenomenon through hardness evolution: the hardness values in the disc center area are higher than at the disc edge area after 1/2, 1, and 3 turns, and the size of the hard region in the disc center gradually reduces as the number of turns increases from 1/2 to 3 turns. The hardness values evolve toward homogeneity along the disc diameters after 5 and 10 turns. Electron backscatter diffraction (EBSD) and X‐ray line profile analysis suggest that the lower hardness values at the disc edge area in the Al–0.1% Mg alloy are related to a recovery/recrystallization mechanism where the material is subjected to heavy straining.
