The International Advanced Research Centre for Powder Metallurgy and New Materials (ARCI), under India's Department of Science and Technology, has successfully used laser powder bed fusion additive manufacturing (PBF-LB/M) to directly deposit stainless steel (SS316L) onto Inconel 718 substrates, producing crack-free, pore-free bimetallic interfaces. Microhardness testing revealed a peak of approximately 310 HV at the interface, with an ultimate tensile strength of 550 ± 30 MPa. Fracture occurred on the softer stainless steel side rather than at the joint, demonstrating excellent interfacial bonding. This technique overcomes issues such as solidification cracking and brittle phase formation caused by mismatches in chemical composition, melting point, and thermal expansion coefficient during conventional welding. It enables expensive superalloys to be used only in areas subjected to the highest thermal loads, reducing material costs and import dependency. Applications span aerospace, nuclear energy, ultra-supercritical thermal power plant boiler tubes, and heat exchangers.
