Summary This paper describes tensile properties of a peak-aged Mg-4Y·3RE alloy at room temperature to 823 K with 10-5 - 10-1 s-1. The Mg alloy exhibited high strength (> 250 MPa) at room temperature to 473 K. However. the strength rapidly decreased at 573 K. It is suggested that a large decrease in strength at 573 K is attributed to grain boundary sliding. Also, elongation increased rapidly at 723 - 823 K. This is likely to arise from the relatively high strain rate sensitivity of about 0.3 due to the glide-controlled dislocation creep.
