Original Abstract

This paper deals with influence of microstructure of magnesium alloy AZ91 on its mechanical properties. Tensile characteristics and microstructures of cast and extruded alloy, and both of these alloys after equal channel angular pressing (ECAP), were compared. It was found that tensile properties are not determined only by grain size but another aspect plays an important role because the highest values of σ0.2 proof stress and tensile strength were achieved for extruded alloy despite its higher average grain size compared to both ECAPed alloys. Compared to this, microhardness seems to be related only to grain size.
