A comparative study on microstructure and mechanical properties near interface for dissimilar materials during conventional V-groove and narrow gap welding
Low alloy steel and 304LN stainless steel was joined by conventional V-groove welding and narrow gap welding. In both welds IN82 was used as consumable. Comparing with existing literature reports, unique aspects of the manuscript may be described as: Detail exploration and explaining microstructural changes across the fusion boundary between LAS and Ni-base alloy using different characterisation techniques like microscopy and X-ray diffraction. Understanding the sequence of deformation and identifying the weakest region across fusion boundary through in-situ tensile test; this was complimented to micro-hardness profile to endorse the inference. Evaluation of work hardening behaviour near FB-1 during plastic deformation under uni-axial loading for a highly heterogeneous assembly. Co-relation between microstructure and mechanical properties.
