Transformation plasticity in 42CD4 steel

This paper deals with the experimental investigation of transformation plasticity of the 42CD4 steel and, mainly, of phases in which austenite can transform during cooling. The aim was to generate data to be implemented in the numerical model of the cooling phase which follows hot forming operations as it was recognized that the accuracy of numerical predictions is sensitively influenced by this parameter. The calibrated numerical model was then validated through on field-measurements and laboratory physical simulations of cooling.
