Abstract

The hot ductility of IMI834 alloy in two conditions of first hot rolling and second hot rolling has been studied by conducting tensile tests with a strain rate of 0.1 s−1 and temperature range of 800–1000 °C. In first hot rolling condition, IMI834 alloy showed little hot ductility in the temperature range 800–900 °C and ductility loss occurred at 850 °C. In second hot rolling condition, hot ductility increased at all temperatures and ductility loss is not occurred. Especially at 900 °C, hot ductility increased from 31% in first hot rolling to 95% in second hot rolling.
