Abstract

Abstract: Inconel 600 super alloy is chromium rich alloy having excellent oxidation and corrosion resistance at elevated temperatures. Due to these excellent properties, it is widely used in aerospace components such as blades, shafts and aircraft gas turbines. To know the high temperature deformation behaviour, Inconel 600 is hot deformed at elevated temperature ranging from 950 °C to 1100 °C with different strain rates range from 0.001 s −1 to 1 s −1 . The true stress-true strain curves are plotted using the data obtained from hot compression. The true stress-true strain curves revealed that the deformation at lower strain rates showing softening for entire range of deformation temperature. Whereas, deformation at higher strain rate revealed strain hardening for entire range of deformation temperature. Softening could be due to dynamic recrystallization (DRX) or the instability in the deformed microstructure.
