Abstract : Ni-based super alloys are metallic materials with exceptional combinations of creep and oxidation resistance at high temperatures. Wrought alloys are hot formed at high temperatures and subsequently annealed and aged. The final mechanical properties of the alloys are a combination of the grain size generated during the process and the precipitation state after aging. In fact, precipitation phenomena are complex for these alloys, which contain up to 12 different elements in their compositions. This study deals with the forming characteristics of Haynes 242. Hot forming is easy to carry out as it requires less efforts but it makes material more dynamic in nature. Haynes 242 was deformed at different temperatures and strain rates. The variation of these parameters on the stress strain flow curves were analysed and study has made on the microstructure evolution and recrystallised grain size.
