چکیده مقاله
In this study, the bonding of IN625 superalloy to 316L stainless steel was investigated using the transient liquid phase TLP bonding process with a BNi 2 interlayer To evaluate the effect of temperature on the microstructure, hardness, and shear strength of the joint, the bonding process was carried out at three temperatures of 1080°C, 1130°C, and 1180°C for a constant duration of 60 minutes Microstructural examinations using optical and scanning electron microscopies SEM revealed the formation of nickel boron rich intermetallic compounds as well as chromium carbides Cr₂₃C₆ in the joint region The formation of these compounds led to an increase in hardness of the diffusion affected zone DAZ and the non isothermal solidification zone ASZ Additionally, shear strength test results indicated that the joint strength increased from 200 MPa for the sample bonded at 1080°C to 350 MPa for the sample bonded at 1180°C The reduction of brittle eutectic phases and the increased uniformity of the formed phases in the joint region played a key role in improving the mechanical properties of the joint This study demonstrates that the TLP process with a BNi 2 interlayer is capable of producing strong and stable joints in dissimilar superalloy to stainless steel bonds, and the optimal selection of temperature and time parameters can significantly enhance the mechanical and structural properties of the joint
