Modeling Volume Changes during Cooling of Case Hardening Steels
(English)Manuscript (preprint) (Other academic)
Results regarding martensitic and bainitic phase transformations, heat expansion behaviors and phase transformation strains during constant heating and cooling rates are presented. Equations describing heat expansion behavior, phase transformation strain and martensitic formation are evaluated as functions of carbon content. The equation for bainitic transformation described in Supplement 2 is used during constant cooling rates for two different case hardening steels. COMSOL Multiphysics is used to simulate experiments, producing good agreement between experimental and simulated dilatometer curves.
