Results of experimental investigations of tool steel during forming in semi-solid state

Semi-solid processes: D. Brabazon

Abstract

The main aims of the work are to determine material characteristics of cold work tool steel, grade 210CR12 in semisolid forming conditions. Methodology of experimental investigation is described in the paper. Nil Strength Temperature (NST) for 210CR12 steel grade was determined. Tensile and hot compression test were performed. The experiments were carried out for different liquid phase fractions, including phase composition adequate to thixoforming. Experiments were carried out on the Gleeble 3800 physical simulator with MAXstrain unit. Results of conducted tests are presented and discussed. Numerical model of hot compression test is presented, as well.
