DYNAMIC MECHANICAL BEHAVIORS OF AS-CAST STAINLESS STEEL 1Cr-25Ni20Si2 DURING HOT DEFORMATION

The dynamic mechanical behaviors of as-cast 1Cr25Ni20Si2 austenite stainless steel during hot deformation for been studied using Gleeble-1500 hot working simulator.The hot deformation equation, the deformation activation energy, the criterion of occurring dynamic recrystallization and the relationship between peak strain and peak stress have been resulted through the experiments.
