大多数含锆的商业镁合金还含有锌，其取决于给定的合金体系从近似0.5%变化到近似6.5%。早期的工作表明，存在3%至5%的锌可以显著增加锆在镁中的溶解度，因此通过锆增强最终合金的增益细化。本文研究了在三种不同温度（680、730和780 ℃）下，锌在0%~ 8%范围内对锆在纯镁中溶解度的影响。还研究了锌单独以及锌和锆的联合作用对纯镁晶粒细化的影响。
Most zirconium-containing commercial magnesium alloys also contain zinc, which varies from similar to 0.5% to similar to 6.5% depending upon the given alloy system. Early work has suggested that the presence of zinc in the range from 3% to 5% could significantly increase the solubility of zirconium in magnesium, therefore enhancing the gain refinement of the final alloy by zirconium. This study investigates the influence of zinc in the range from 0% to 8% on the solubility of zirconium in pure magnesium at three different temperatures (680, 730 and 780degreesC). The effect of zinc alone as well as the combined effect of zinc and zirconium on the gain refinement of pure magnesium is also investigated.
