The mechanical behaviour and development of microstructure in tension of an Al-4.5% Mg alloy at temperatures from 450 to 570°C and strain rates from 10−6 to 10−2 s−1 has been investigated. High strain rate sensitivities, up to m = 0.7, but relatively small elongations, between 120 and 280%, were obs...
