| 中文摘要: |
| 施密特因子具有计算简单、表述方便的优点,在金属微观塑性变形机理分析中,能够定性判断微观变形模式滑移和孪晶的启动。首先介绍了施密特因子在密排六方晶体结构中的多种表述形式,然后分别列出了其在镁合金塑性变形微观机理分析中的应用。上述应用结果表明,施密特因子在镁合金变形机理研究中是不可缺少的工具。 |
| 英文摘要: |
| Schmid factor has advantages of easy calculation and convenient description, which can quantitatively predict activations of deformation micro-modes sliding and twinning. In this paper, some description ways of Schmid factor were first introduced, and application of Schmid factor in analyzing Mg alloy deformation micro-mechanism were also listed, which shows that the Schmid factor was an indispensible tool in Mg alloy deformation mechanism investigation. |
