“…Trojanová et al (2005) present similar results for a number of rare earth alloys, including alloy ZE41 (where E denotes an Ndrich rare earth mischmetal). Finally, Wang et al (2007) present a historical overview of DSA observations in magnesium, along with a presentation centered on alloy ZE43 (where E denote Ce-rich mischmetal). None of the characteristics of DSA, such as serrated flow, reduced strain rate sensitivity or yield strength anomaly, have been observed for the present ZW41 alloy sheet (Agnew et al, 2008).…”

“…These three alloys exhibit serrations when they are tested in the peakaged condition. It was pointed out [22,23,27] that there are enough solute atoms in the magnesium matrix even in this peak-aged condition to repeatedly pin and unpin gliding dislocations to produce the serrations. Wang et al [26] reported the serrated flow of a Mg-Li alloy that exhibited positive strain rate sensitivity (SRS) at lower strain rates and negative SRS at higher strain rates.…”

“…In the past few years, the serrated flow has been reported to occur in several magnesium alloys, including WE54, Mg-Ca-Zn-Zr, AZ91, Mg-Nd, Mg-Li(-Al), ZE43, and Mg-Y. [22][23][24][25][26][27][28] The dynamic strain aging (DSA) model is used to explain the serration in the WE54, Mg-Ca-Zn-Zr, and ZE43 alloys. These three alloys exhibit serrations when they are tested in the peakaged condition.…”

“…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.…”
