【摘要】 采用改进的KF -CsF -AlF3 中温无腐蚀钎剂与Ag -Al-Cu -Zn中温钎料实现了对LY12铝合金的中温钎焊 ,钎焊接头的抗剪强度可达到母材强度的 80 % ,对接接头钎缝的抗拉强度可达到母材强度的 70 % ,突破了“热处理强化铝合金通常不能钎焊”的传统论断。更多还原

【Abstract】 The technology for brazing LY12 Al alloy at middle temperature is realized by improved KF CsF AlF3 flux matching Ag Al Cu Zn filler metal.The τ and σ b strength values of brazed joints,are about 80% and 70% respectirely as compared with the base metal.A way out of the conclusion is found that heat treated Al alloy could not be brazed under normal conditions by the results.更多还原
