INFLUENCE OF Ce ADDITION ON THE MICROSTRUCTURE AND HOT-PROCESSING MAPS OF Mg-1Ca-0.5Mn ALLOYS
Keywords:
Mg-Ca-Mn alloy, Ce addition, hot compression, processing map
Abstract
To investigate the processability of Mg-1Ca-0.5Mn alloys with and without the addition of Ce, hot-compression tests were performed on a Gleeble-3800 thermo-mechanical simulator at 300–450 °C and 0.001–5 s–1. The flow stress, processing map, and microstructure characterization of the alloys were investigated. The results show that the flow stress of the Mg-1Ca-0.5Mn-0.5Ce alloy was significantly improved for all the thermomechanical deformation parameters, and the dynamic recrystallization phenomenon was delayed. This phenomenon was attributed to the finer grains and the dense distribution of the fine and coarse particles pinned at the grain boundaries. The processing map shows that the Mg-1Ca-0.5Mn-0.5Ce alloy has better processing performance at a low strain rate.
