Abstract

Constraint uniaxial compression of magnesium single crystals along c-axis was carried out at room temperature and elevated temperatures of up to 500 ℃. The deformation structures were characterized by electron backscatter diffraction (EBSD). The results showed no evidence of pyramidal <c+a> slip and twinning was responsible for plastic deformation in the range of temperatures tested. The atomic configurations and crystallographic features associated with pyramidal <c+a> dislocations were revealed with the help of CrystalMaker software and a possible <c+a> dislocation core structures was reconstructed. The crystallographic analysis suggested that pyramidal slip was difficult because <c+a> dislocations would involve too many atoms on irrational lattice planes and directions.
