Abstract

The effect of grain size on the tensile deformation of Mg-MM-Al-Zn-Sn (EAZT211) alloy sheet has been investigated. Specimens with grain size varying from ~ 10 to ~ 20 μm have been obtained by altering the annealing conditions after rolling. The yield strength of EAZT211 sheet exhibits grain size dependence according to Hall-Petch relationship from room temperature to 200 °C. Occurrence of yield phenomenon and decrease of Hall-Petch slope (k) with increasing strain suggest that non-basal slip system operates during deformation. In addition, deformation mechanism changes from slip mechanism to grain boundary sliding mechanism at ~ 150 °C.
