Bimetallic applications on functional parts produced via additive manufacturing methods have been worked by my researchers in order to obtain multi-directional benefits. One of the most compatible bimetallic application is the combination of SS316 and Inconel 718 pair which has a potential application in aerospace, energy and chemical industries. In this study, SS 316 deposited on the Inconel 718 substrate and Inconel 718 deposited on the SS 316 substrate by directed energy deposition additive manufacturing method were investigated. The bonding characteristics and performance, microstructure, micro hardness behavior at bonding region were examined in detail. Since the melting points and thermal conductivity of the binary materials are not very different, bonding was generally considered successful in terms of delamination. On the other hand, in the microstructure examinations, intermetallic structures that deteriorate the material characteristics were encountered and it was determined that these structures caused regional cracking and changes in the micro hardness values.
