The improvement of YTS is attributed to the grain refinement strengthening of Y and Zn, and to the solid solution strengthening of Zn. The reduction of UTS and elongation are caused by the precipitation of a compound phase along the grain boundary.

Y、Zn元素的细晶强化及Zn元素的固溶强化是屈服强度提高的主要原因；抗拉强度和延伸率的降低是由于化合物相沿晶界析出。
