研究了锆含量对镁锌合金晶粒度的影响。结果表明,在镁锌合金中添加锆能细化镁锌合金的晶粒度,添加量为0.6%时,镁锌合金的晶粒度从145μm细化到42μm。晶粒细化后材料的伸长率从5.3%提高到9.3%,抗拉强度从149 MPa提高到169 MPa,硬度从76.3 HB提高为86.3 HB。
The effect of zirconium content on the grain size of magnesium-zinc alloy was studied. The results show that the addition of zirconium to magnesium-zinc alloy can refine the grain size of magnesium-zinc alloy. When the addition amount is 0.6%, the grain size of magnesium-zinc alloy is refined from 145μm to 42μm. After the grain refinement, the elongation of the material increased from 5.3% to 9.3%, the tensile strength increased from 149 MPa to 169 MPa, and the hardness increased from 76.3 HB to 86.3 HB.
