Original abstract

This paper deals with tensile properties of magnesium alloy AZ91 at elevated temperature. Properties of alloy in extruded state and after additional equal channel angular pressing (ECAP) are compared. Tensile tests were performed at room temperature and at elevated temperature in the range of 100 to 300 °C. It was found that all analyzed properties (0.2 proof stress, ultimate tensile strength (UTS), elongation and reduction of area) of alloy in both states were comparable but slightly lower for alloy in exECAPed state at room temperature. At elevated temperature 0.2 proof stress and UTS of extruded alloy decreased and elongation and reduction of area increased. Properties of exECAPed alloy exhibited similar trends but more intensive. The difference was most evident in increase of elongation which exceeded 260% for exECAPed alloy while for extruded alloy reached barely 100%.
