Magnesium alloy TX32 (Mg-3Sn-2Ca) has good corrosion and creep resistance. The processing map of TX32 exhibits a good workability domain over a fairly wide range of temperature and strain rate. To validate the processing map, spike forging of the alloy (combining backward extrusion and upsetting) was carried out at the temperatures of 400, 450 and 500 °C and at speeds of 0.1 and 1 mms-1. Finite-element (FE) simulation of the process was conducted using DEFORM-2D software to obtain the local variations of strain and strain rate. It has been found that the strain values reach as high as 1.8 at certain locations in the forged components. The average grain size has increased with increasing temperature and decreasing speed. The microstructure varied at different regions of the forged components as per the implied features of the processing map and FE simulations, with recrystallized fine grain sizes at locations corresponding to higher strains and strain rates.
