Abstract
The tension-compression asymmetry in a randomly textured cast magnesium alloy is investigated in terms of its {10-12} twinning characteristics. This {10-12} twinning behavior, which governs the initial stages of deformation, is found to be notably different under tension and compression, consequently resulting in a lower yield strength and higher strain hardening under tension than compression. An interpretation of this behavior is provided through subsequent analysis of the Schmid factor, the grain fraction favorable for twinning, and the dominant twinning mechanism.
