Hot deformation behavior of 9Cr-1Mo ferritic steel has been studied in a wide range of temperatures (900-1200°C) and strain rates (0.01-10s-1). Using the true stress-strain data obtained from isothermal hot compression tests, a constitutive modeling has been developed. The flow stress increased with...
