The microstructure and mechanical properties of Mg₉₄Zn_2.5Y_2.5Mn₁ (at%) with different Ti contents were investigated. The addition of 0.3 at% Ti yielded the best strength. However, Mg_93.5Zn_2.5Y_2.5Mn₁Ti_0.5 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).

添加Ti对Mg-Zn-Y-Mn合金LPSO相形成及屈服不对称的影响

研究了不同Ti含量的Mg ₉₄ Zn _2.5 Y _2.5 Mn ₁（at％）的显微组织和力学性能。添加0.3原子％的Ti产生最佳的强度。然而，Mg _93.5 Zn _2.5 Y _2.5 Mn ₁ Ti _0.5表现出最低的产率不对称性。这些变化归因于晶粒细化，LPSO相增加和轴向比降低（c / a）的综合作用。
