Effect of Aging Heat Treatment on the Microstructure of Gas Tungsten Arc-Welded Inconel Superalloy 7 effect of heat treatment time on the microstructure was evaluated. Gamma prime (γʹ), gamma double prime (γʺ) and the primary carbides of MC, M.C. were observed in the HAZ and grain boundaries. It was observed that with the increase in aging time microhardness was significantly increased. The mechan
