Abstract Scope |
Wrought-processed Mg-Y-Zn alloys with long-period stacking ordered (LPSO) phase have exhibited high strength. The high strength is suggested to be related to the deformation kink bands formed by the wrought process. In the present study, hot compression tests were carried out on four types of cast Mg-Y-Zn alloys with the different volume fraction of the LPSO phase. After compression tests, deformation kink bands were observed in the LPSO phases, and the morphology differed depending on the compression temperature and the volume fraction of the LPSO phase. As the results of the hardness tests, the hardness shows a tendency with the increase of compressive strain or decrease of compression temperature. We discussed the microstructure including the morphology of the deformation kink band and the hardness. |
