Super alloys are basically used in high temperature industrial applications due to their resistance to aggressive environments and longer durability than other conventional alloys. In this research, the dissolution behavior of primary gamma prime precipitates has been analyzed under various solution heat treatments via making changes in the time and temperature of the Standard Heat Treatment (SHT) and subjecting the specimens to external compressive stress. The microstructures were examined by Scanning Electron Microscope (SEM) and afterwards the diameters and the numbers of
