| 中文摘要: |
| 目的 研究轧制变形程度对AZ31镁合金板材组织和性能的影响。方法 主要设计了轧制变形程度分别为51%， 63%， 72%的3组轧制工艺并进行实验， 然后观察不同轧制变形程度下板材退火后的微观组织及力学性能。结果 当轧制变形程度72%时， 晶粒最细， 抗拉强度和断裂延伸率最高。结论 随着轧制变形程度的增加， 镁合金板材晶粒逐渐细化， 而抗拉强度和断裂延伸率随着轧制变形程度的增加而提高。 |
| 英文摘要: |
| In order to study the effects of different rolling deformation degree on the microstructure and property of AZ31 magnesium alloy sheets， three groups of rolling processes with rolling deformation degrees of 51%， 63% and 72% were designed in the present work. The microstructure and mechanical properties of annealed sheets with different rolling deformation degree were observed. The results showed that: when the rolling deformation degree was 72%， the grains were fine， and the tensile strength and elongation were the highest. Finer grains were achieved with increasing rolling deformation degree and the tensile strength and elongation increased with increasing rolling deformation degree. |
