Twinning-mediated plasticity by a novel multistage twinning mode in an Mg-Al-Gd alloy
Twinning-mediated plasticity has great potential for enhancing the strength and plasticity of Mg alloys
which is limited due to the lack of twin types. Here
we report a novel multistage twinning mode
i.e. the dominant twinning mode changes from single {101¯2} twins to the co-existence of {101¯2} and {112¯6} twins
in a deformed Mg-Al-Gd alloy. Introducing novel multistage twinning mode to accommodate strains appreciably along
c
-axes
combined with the interactions of high-density dislocations and dense twin boundaries
guarantees the high strain hardening of Mg alloys. These findings provide new insights into deformation mechanisms and mechanical properties of Mg-alloys.
