Microstructural evolution and mechanical properties of LM6 Al alloy

Abstract

In this paper, multi-axial compression of LM6 Al alloy were performed at room temperature using strain of 0.2 in each pass. Total cumulative strains 0.6, 1.2 and 1.8, were applied in three, six and nine passes, respectively. Microstructural evolution is studied using light optical microscopy of the compressed specimen. Properties (tensile strength, hardness, toughness) of deformed specimens were studied using tensile and hardness tests, and relate them with their microstructures and fractographs. As passes increased from zero to nine, 62% of tensile strength of the material is increased along with hardness from 52 VHN to 74VHN
