High temperature creep of steel 09G2S under non-stationary loading

Experimental analysis of deformation of steel 09G2S under creep conditions has been carried out to determine the optimal modes of high temperature forming of steel shells. The efficient temperature range in terms of saving of the plasticity resource was defined. The material parameters including sca...

Description
Summary:Experimental analysis of deformation of steel 09G2S under creep conditions has been carried out to determine the optimal modes of high temperature forming of steel shells. The efficient temperature range in terms of saving of the plasticity resource was defined. The material parameters including scalar damage parameters have been determined by taking into account the description of the deformation of a material under non-stationary loading conditions. A satisfactory description of the unsteady creep processes of the material 09G2S in the temperature range from 700 to 800°C has been received.
