摘要：
High quality fabricating of the bimetallic structure of TA15 and Inconel 718 (IN718) is widely used in the aerospace filed. In this study, we have used laser additive manufacturing (LAM) technology to fabricate the bimetallic structure and to prevent the formation of brittle phases via Nb/Cu multi-interlayer. The results of this study showed that Nb/Cu multi-interlayer was very effective in preventing the generation of brittle Ti-Ni and Ti-Cu phases. The good metallurgical bonds were presented at these interfaces between TA15 and IN718. Mechanical properties of the bimetallic structure revealed that the tensile strength reached that of the weakest metal, Cu.
