| 摘 要： | 研究了Al元素含量对Zn-Al钎料在铝—铝钎焊及铜—铝钎焊过程中的铺展性能、接头力学性能及显微组织的影响.结果表明,随着Al元素含量的增加,钎料在铝板上的铺展性能明显改善,当Al元素含量达到15%(质量分数)时铺展面积最大,继续增加Al元素含量,铺展面积减小.Al元素含量在2%～25%范围内,钎料在铜板上的铺展性能随Al元素含量增加呈上升趋势,但是Zn-Al钎料在铜板上的铺展性能显著低于在铝板上的铺展性能.钎焊接头力学性能试验表明,铝—铝对接接头的抗拉强度以及铜—铝钎焊接头力学性能均随着Al元素含量增加而逐渐增大,当Al元素含量达到15%时强度达到最高,继续增加Al元素含量,钎焊接头强度均逐渐降低. |

| Abstract: | Effects of Al on the spreadability of Zn-Al filler metal were investigated,moreover,the strength and microstructure of the brazed joint had been studied by brazing Al-Al and brazing Cu-Al.The results indicated that when Al content was 15%,the filler metal got the best spreadability on aluminum substrate.However,the spreadability decreases when Al content exceeded 15%.It was also found that the spreadability on copper substrate increased with the increase of Al content when Al content was changing from 2% to 25%.The spreadability on copper substrate was much lower than that on aluminum substrate.Furthermore,the mechanical property tests indicated that the strength of the butt joint of Al-Al and the joint of Cu-Al including the lap joint and the butt joint enhanced with the increase of Al content.The highest strength of the brazed joint was obtained when Al content was 15%.However,when Al content exceeded 15%,the strength of the brazed joint decreaseed. |
| Keywords: | brazing Al-Al brazing Cu-Al Zn-Al fill metal spreadability mechanical property |
