Abstract

Abstract: Pyramidal I slip was observed to be the dominant slip mode in magnesium single crystals compressed quasi-statically along c-axis at room temperature. The slip trace angles resulted from pyramidal I and pyramidal II slips projected on (0 − 1 1 0) and (2 − 1 − 1 0) surfaces were initially calculated, and then measured on 3% deformed magnesium single crystals. The measured angles indicate the prevalence of pyramidal I slip ({10–11}< 11–23 > with the critical resolve shear stress of 54 MPa). The pyramidal slip traces are dense but very fine, suggesting limited < c + a > dislocation activities. Graphical abstract:
