• magnesium single crystal
• basal slip
• prismatic slip
• twin
• critical resolved shear stresses (CRSS)

With a hexagonal close packed structure, magnesium has many slip systems. Pure shear tests were carried out to evaluate their critical resolved shear stresses (CRSS). As a result, the CRSS for the basal slip was 0.7 MPa, and it was close to conventional values. When the shear stress of 40 MPa was applied in parallel to the prismatic plane, the {10 (1) over bar2} twin deformation occurred only, and the prismatic slip deformation did not occur.
