| 中文摘要: |
| 目的 研究搅拌道次对 6061 铝基碳化硅复合材料的影响。 方法 对 6061 铝基碳化硅复合材料进行了搅拌摩擦焊实验。 结果 获得了型面良好,表面光滑的焊接截面,焊核区组织为细小的等轴晶,热机影响区为弯曲变形的晶粒,热影响区组织发生了明显的粗化。 结论 搅拌次数越多,SiC 颗粒分布越均匀,热机影响区与热影响区附近硬度最低,热影响区硬度较低,焊核区硬度比母材稍高。 |
| 英文摘要: |
| The aim of this study was to investigate the influence of Stirred passes of 6061 SiC composites by FSW. The FSW experiments were carried out on 6061 silicon carbide composites. Good surface and smooth surface welding section was acquired, fine equiaxed grains were formed in nugget zone, and significant coarsening was observed in HAZ. SiC parti- cle distribution was more uniform with more times of stir. There was minimum hardness near the heat affected zone, and the hardness in weld nugget was slightly higher than that of base metal. |
