Abstract
Rapidly solidified Al-10Mg-0.8Zr pre-alloyed powder have been produced by a rotating disk atomization method. Tensile strength and elongation of the extrudate prepared from the powder have been evaluated at elevated and room temperatures.<BR>The tensile strength and the elongation of the extrudate at room temperature are 540MPa and 28%, respectively, and these values are comparable to those of high strength aluminum alloys, for example, A7075 with T6 treatment. The specific strength of the extrudate is 208MPa⋅m3/Mg, which is comparable with high strength titanium alloy. The elongation of the extrudate increases with increasing strain rate in the temperature range between 400 and 480°C, and the optimum strain rate showing the maximum elongation is more than 4.2×10-1 s-1. The maximum elongation is 185% at an initial strain rate of 4.2×10-1 s-1 at 480°C.
