The dominant deformation mode at low temperatures in magnesium and its alloys is generally regarded to be twinning because of the hcp crystal structure.More recently, the phenomenon of a "loss" of twins has been reported in microcompression experiments on magnesium single crystals, while significant plasticity and hardening occurred due to six active pyramidal slip systems [1,2].These results pointed to an intriguing deformation pattern of magnesium single crystal at the nanoscale, namely no deformation twins are present in the microcompression deformed specimens.This is in contrast to observations on bulk samples indicating the deformation twinning is the primary mechanism for c-axis compression.
