DYNAMIC MECHANICAL BEHAVIOURS OF HIGH Mo AUSTENITIC STAINLESS STEEL DURING HOT DEFORMATION

摘要

The dynamic mechanical behaviours of super low carbon high Mo austenitic stainless steel(00Cr20Nil8Mo6CuN)during hot deformation have been studied by using Formaster-Presshot working simulator. The hot deformation equation, as well as the relationship between peakstrain, peak stress and Zener-Hollman parameter, together with the deformation activationenergy have been resulted through the experiments.
