| 摘 要： | 研究了Fe3A1基金属间化合物合金的室温变形和高温蠕变特点。结果表明，Fe3A1合金室温形变将发生诱导无序化现象.蠕变过程中不仅发生形变诱寻无序化现象，而且发生蠕变加速有序转变现象，形变诱导存序显微结构变化将淡化原始结构对蠕变断裂寿命的影响.

| Abstract: | The stain-induced microstructural changes of Fe3Al-based alloys during room temperature deformation and high temperature creep were investigated. The results illustrated the strain-induced disordering occured during room temperature deformation. Creep strain could induced two opposite processes, which are strain-induced disordering and creep recovery-induced reordering. These two opposite creep induced processes during creep result in reducing the influence of primary microstructure on the rupture life. |
