In recent years Mg-Zn-Y series alloys have drawn significant interest due to their superior mechanical properties. The addition of yttrium to the Mg-Zn alloy leads to the formation of a special phase (Mg12YZn) with a long-period stacking ordered (LPSO) structure, which plays an important strengthening role. The main aim of this study was to identify the deformation mechanisms of LPSO phase in an as-extruded yttrium-containing magnesium alloy. On the other hand, the successful manufacturing of magnesium alloy components requires the optimal hot working parameters. The processing map is an effective tool which can be used to pinpoint the optimal processing regions and the instability regions which should be avoided. Thus, the other objective of this study was to evaluate the hot deformation behavior of a Mg-Zn-Mn-Y alloy via isothermal compression testing at different temperatures and strain rates. The processing maps were constructed and the optimal hot processing conditions were identified.
