Effects of Ti addition on the formation of LPSO phase and yield asymmetry of Mg-Zn-Y-Mn alloy

Effects of Ti addition on the formation of LPSO phase and yield asymmetry of Mg-Zn-Y-Mn alloy

The microstructure and mechanical properties of Mg94Zn2.5Y2.5Mn1 (at%) with different Ti contents were investigated. The addition of 0.3 at% Ti yielded the best strength. However, Mg93.5Zn2.5Y2.5Mn1Ti0.5 exhibited the lowest yield asymmetry. These changes were attributed to the combined effects of g...

Zusammenfassung:The microstructure and mechanical properties of Mg94Zn2.5Y2.5Mn1 (at%) with different Ti contents were investigated. The addition of 0.3 at% Ti yielded the best strength. However, Mg93.5Zn2.5Y2.5Mn1Ti0.5 exhibited the lowest yield asymmetry. These changes were attributed to the combined effects of grain refinement, increased LPSO phase, and reduced axial ration (c/a).
