摘要
为缓解钎焊接头的残余应力 ,人们提出了在普通钎料中加入一定体积比的作为增强相的各种形态的高温合金、碳纤维及陶瓷颗粒等形成复合钎料的方法。该钎料不仅具有较好的填缝能力 ,同时获得的钎缝接头具有良好的高温强度和抗冲击性能。
Composite brazing filler metal, which provided by adding super-alloys, carbon or ceramic particulates of certain volume ratio as wild phase to common brazing filler metal, was used to alleviated the welding residual stress. This kind of brazing filler metal had a good filling performance, at the same time, sound high-temperature strength and impact toughness can be obtained in the joint.
