N2 - The hot working characteristics of as-cast Mg-3Sn-1Ca alloy have been studied using processing-map technique and the kinetic rate equation. The map exhibited two domains; one in the lower strain rate range (0.0003-0.01 s- 1) and the other in the higher strain rate range (0.1-10 s- 1)-both falling in the same temperature range of 350-550 s- 1. Hot extrusion at 500 °C and a speed corresponding to an average strain rate of 3 s- 1 exhibited dynamically recrystallized microstructure. The estimated apparent activation energy values are higher than those for self-diffusion in pure magnesium suggesting that the large volume fraction of MgSnCa intermetallic particles causes significant back stress.
