摘　　要：研究了采用镍基含硼钎料钎焊IC -6合金时 ,接头近缝区出现的硼化物相的形貌、成分及结构 ,结果表明主要存在两种成分的硼化物相 ,r(Ni) :r(Mo)分别近似为 1 :1和 1 :2 .硼化物取向有一定规律 .对接头近缝区与合金中硼化物的形貌、成分进行了对比 .When brazing IC-6 superalloy using nickel base brazing alloy with boron as melting point decrement, boride phases would form at the interface. In this paper, their morphology, composition, and structure were studied respectively. Furthermore, Boride phases at the interface were compared with that formed in the base metal.
