Mechanical behaviour of stainless steel under warm working conditions

A rational description of the constitutive behaviour of Kh18N9T stainless steel deformed between 870 K and 1120 K, over a wide range of strain rates, is proposed. Results regarding the change in saturation stress with temperature and strain rate indicate that dynamic strain aging effects, associated with negative values of the strain rate sensitivity of the saturation stress, are present in the temperature range 870-1070 K and strain rates of the order 0, 1 -10 s^-1.
