Development of processing maps for 3Â vol.% TiCp/AZ91D composites material

The hot deformation behaviour of TiCp/AZ91D magnesium matrix composites were investigated by means of hot compression test and processing map at the temperature ranging from 250 to 400 °C with the strain rate varying from 0.001 to 10 s−1. The hot processing map of TiCp/AZ91D magnesium matrix composites revealed that a domain of dynamic recrystallization (DRX) occurred in the temperature range of 270-320 °C and strain rate range of 0.001-0.01 s−1, with its peak efficiency of 36% at 300 °C and 0.001 s−1, which were the optimum hot working parameters.
