| 摘要: |
| 本文研究了S147铝合金板材在形变时效处理各工艺阶段中的组织与性能。用扫描电镜观察分析了材料的断口形貌，并用薄膜试样在透射电镜下分析研究了该合金形变时效处理后的微观亚结构及过渡相析出物特征。结果表明，最佳形变时效处理可显著提高S147铝合金的强度及塑韧性，并能改善其过渡相析出过程及特征。 |

| Abstract: |
| The microstructure and the properties of S147 aluminum alloy plate at each stage of deformation aging have been studied. The fracture aspects of the material have been analyzed and examined with a SEM. The microstructures and features of transition phase precipitates of S147 aluminum alloy after deformation aging have been analyzed and investigated with thin foil Specimens by TEM. The results show that the optimun deformation aging Can greatly increase the strength，plasticity and toughness of S147 aluminum
alloy，and improve the feature and process of trousition phase precipitates. |
