Modeling phase transformations and volume changes during cooling of case hardening steels. Licentiate thesis.

Author(s) : TEHLER M.

Type of monograph: Doctoral thesis

Summary

Case hardening distortions are a major problem for gear manufacturers. The aim of this work is to create a simulation model, able to predict how and when case hardening distortions arise. The results presented in this licentiate thesis form a basis for such a model. Two case hardening steels, with base carbon contents of 0.20 and 0.21% C were studied using dilatometer experiments.
The results were used to evaluate phase transformations, heat expansion behaviour and phase transformation strains. The expansion behaviour of the material has been modelled as a function of temperature, carbon content and phase fractions.
