| 摘 要： | 在激光焊接条件下，分析丁20％SiCw／6061铝基复合材料焊缝表面及内部特性，指出在激光焊接条件下，铝基复合材料的焊缝较窄、深宽比大；焊缝可分为焊缝中心焊接区、熔化区及来变化区三部分；在中心焊接区内有大量Al4C3生成，造成焊缝较脆，窖易断裂。

| Abstract: | The exterior and interior characteristics of welding beadof laser welded 20%SiC/6061 aluminum matrix composites were studied.Laser welded the bead of aluminum matrix composites was nalTow and theratio of pentration and width was great.The welding bead could be dividedinto three parts:the center melt reaction section and melt unreaction sec-tion and heat affeted section.Many A14 C3 platelets were created in thecenter melt reaction section and made the welding bead brickle and easyto be ruptured. |
