| Abstract | In this study, laser brazing of precipitation hardening nickel-based alloy (Inconel 718) and solid-solution nickel-based alloy (Inconel 600) with the nickel-based filler metal (BNi-2) using a 400-W pulsed Nd:YAG laser was investigated. A laser brazing process was performed at different gap distances. Microstructure and composition analysis of the filler metal and the brazed joints were examined by optical microscopy (OM) and scanning electron microscopy (SEM) equipped with an energy-dispersive X-ray spectroscopy (EDS). Mechanical properties of the brazed joints were measured in the form of micro hardness and tensile test. Results show that the filler metal consists of nickel solid solution, nickel-rich boride, and chromium-rich boride. The laser-brazed joints are mainly comprised of the nickel solid solution, nickel-rich boride in the center of the joints, and chromium-rich boride near the interface with substrates. The filler metal shows good wetting and spreading on Inconel 718 and Inconel 600 substrates in a laser brazing process. The average micro hardness for the filler metal was 550 HV compared to 500 HV for the laser-brazed joints. The tensile strength of the laser-brazed joints varied from 200 up to 500 MPa because of different gap distances. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
