Temperature–related assessment of the fatigue creep behavior of the additively manufactured magnesium alloy WE43 in the compression regime

Abstract

Current efforts in additive manufacturing commonly use magnesium alloys because of their numerous advantages. Despite these, the performance of magnesium at high temperatures often limits operational conditions. This study investigates the high–temperature performance of the additively manufactured WE43 magnesium alloy, with a particular focus on its creep behavior under quasistatic and cyclic compression loading at elevated temperatures. The results show that manufacturing–related defects result in reduced creep resistance and affect the fatigue capability.
