“…DSA is normally revealed by the appearance of a serrated flow in the stress-strain curve. DSA was detected in many magnesium alloys (some of them Mg-RE) deformed not only by tensile tests (Couling, 1959;Chaturvedi et al, 1972;Chaturvedi and Lloyd, 1974;Corby et al, 2004;Wang et al, 2006;Zhongjun et al, 2007;Wang et al, 2007;Fang et al, 2009;Gao et al, 2009a;Wu et al, 2012;Cai et al, 2014;Garcés et al, 2015;Wang et al, 2015;Wang et al, 2017) but also by compression and torsion tests (Stanford et al, 2010;Jiang et al, 2011;Garcés et al, 2018). The dynamic interaction between RE atoms with dislocations and twinning are the main responsible for its appearance.…”
