PRELIMINARY INVESTIGATION INTO MECHANICAL PROPERTIES AND MICROSTRUCTURAL BEHAVIOUR OF INCONEL ALLOY UNDER WELDED AND UNWELDED CONDITIONS

This work focusses on analysing mechanical properties and microscopic assessment into Inconel-718 plates in welded unwelded conditions. Welding was performed by tungsten inert gas welding technique. Two tests such as tensile test hardness were both the types of to compare joint plate. Although Inconel 718 possesses good weldability, strength, ductility, reported lesser than these Unwelded The microstructural images revealed that metal carbides present plate had reduced after welding. ultimate stress elongation before breaking 16% 72% lower fractography analysis ruptured part possessed higher ductility
