The both positive and negative effect of pre-strain on the mechanical response of extruded magnesium alloy

Abstract

The Mechanical response of magnesium alloy is highly dependent on the texture especially in extruded magnesium alloys. Here in this study pre-compression was applied up to different strain levels and its effect on the stress-strain response has been observed. Our result illustrated that the pre-compression increased compressive yield strength, ultimate compression strength and ultimate tensile strength; however the tensile yield strength was significantly decreased.
