In this paper, the various interactions between the different parameters involved during quenching, i.e. temperature, phase transformation, and stress–strain, are investigated and a constitutive model of the material during the process is presented and discussed. The influence of the parameters has been studied, by computer calculations using a constitutive model, for three steel cylinders, and the results indicate that in some cases the constitutive model seems important. In none of the cases studied in the paper is the influence of the stress state on the transformation kinetics very great.
