In the present study, superplastic behavior of a pseudo single phase magnesium alloy, ZK61, was investigated at about half the absolute melting point. The material was produced by the P/M route, and had a fine grain size of [approximately]500 nm. It is demonstrated that the P/M ZK61 alloy can behave in a superplastic manner at a high strain rate of 1 [times] 10[sup [minus]2] s[sup [minus]1] albeit at the low temperature.
