Uniaxial tension and compression behavior of AZ31 magnesium alloy rolled and extruded materials

Abstract

Mg alloy as a practical use metal is superior in specific strength and specific stiffness, and also exhibits eminent performance in heat discharging, electromagnetic wave shielding and vibration and shock absorption. Therefore, it is used for the components of cars, aircrafts, precision machines etc. and its applications are broadened to various fields. Mg alloy AZ31 rolled sheet and extruded sheet were considered in this study. It was the experimental observation and investigation of the deformation behavior about the materials manufactured different methods by uniaxial tensile test and compression test under the temperature range including high temperature range. It was also aimed at revealing and investigating the differences of material properties derived from different manufactured methods. A Siebel-type compression test was performed, which can compensate the deviation from a simple compression condition caused by the friction between interfacial surfaces of tools and materials, in order to perform the test based on ideal simple compression condition. The properties of material received by both tests were compared and important findings were obtained for Mg alloy AZ31 sheet.
