Constitutive analysis for hot working of modified 9Cr-1Mo (P91) ferritic steel was carried out employing experimental stress-strain data from isothermal hot compression tests, in a wide range of temperatures (1123-1373 K), strains (0.1-0.5) and strain rates (10 À3 -10 2 s À1 ). The effects of temper
