Revealing the role of pyramidal slip in the high ductility of Mg-Li alloy

Journal of Magnesium and Alloys 2024年第3期12卷 1021-1025页

The high ductility of Mg-Li alloy has been mainly ascribed to a high activity of pyramidalslip to accommodate plastic *** the present study,however,a quantitative analysis reveals that Li-addition can only slightly stimulate the activation of pyramidalslip under compression along the normal direction of a hot-rolled Mg-4.5 wt.%Li plate,with a relative activity of approximately 18%.Although the limited activity of pyramidalslip alone cannot accommodate a large plastic strain,it effectively reduces the number of{10.11}−{10.12}double twins,which are believed to be favorable sites for crack *** evidently reduced activity of double twins leads to a lower cracking tendency,and therefore improves ductility.
