Abstract

Diagrams for determining weight fractions of pearlite and martensite, transient and residual thermal-hardening stresses are numerically evaluated and analysed for steel plates. Kinetics of phase transformation and the accompanying volumetric dilatation are taken into account. The diagrams enable the evaluation of proportions of individual constituents and phases, determination of relative volumetric changes due to phase transformations, and estimation of transient and residual stresses. The results are obtained and compared for Lomakin's theory and the Hildenwall model.
