Abstract Scope |
The improved formability of advanced Mg sheet alloys has been attributed in part to their off-basal textures with a relatively low texture intensity. We have investigated the thermomechanical processing variables that produce these desirable textures in a systematic study of Mg-Zn-Ca alloys subjected to plane strain compression (PSC) using a Gleeble Thermomechanical Simulator. The PSC thermomechanical processing (TMP) route used consists of multiple compressive “hits” intended to simulate a multi-pass rolling process. This work utilizes microscopy and electron backscatter diffraction to track the evolution in microstructure and crystallographic texture that occurs during TMP at multiple stages in the processing path. We have demonstrated that the thermal soaks between passes and static recrystallization during the final annealing treatment play a particularly important role in determining the final texture. The effect of alloying and changes in processing conditions on the final texture are also important and will be discussed. |
