The anisotropic effects on the microstructure and mechanical response of rolled magnesium alloy Mg–3Al–1Zn in the H24 condition have been quantified. Strong strain rate dependences on the compressive yield, hardening rate and ductility were observed in the normal direction, while the rolling and transverse directions exhibited no strain rate dependence on the yield strength, but did show a marked increase in hardening at a characteristic strain level. The microstructural characteristics associated with the different mechanical property tests were also determined.
