Effect of Texture and Microstructure on Ductility of a Mg-Al-Ca Alloy Processed by Equal Channel Angular Pressing
Texture and microstructure formation during equal channel angular pressing (ECAP) of Mg-0.49%Al-0.47%Ca alloy were studied. The selected ECAP condition (route BC, N=6 passes, true strain ε ≈ 6.8, T=300°C) ensures an ultrafine-grained structure of the alloy and basal texture, inclined at an angle of 45-55º relative to the direction of extrusion. The expectation that such a change of the texture, together with the refinement of microstructure, should improve the low temperature ductility of this material was confirmed by tensile testing.
