Abstract
Coupling effects between temperature field and structural changes were considered in the analyses of structural changes and stresses due to quenching of steel from the viewpoint of continuum thermodynamics. A heat conduction equation with latent heat was derived by employing the mass fractions of structural components, and a finite element calculation was carried out to obtain the temperature and structural distributions.
An elastic-plastic constitutive relation was presented considering the effect of dilatations due to phase changes as well as temperature variation, and stresses were analysed by the finite element method. The results calculated were compared with the experiments for a cylinder of 0.43%C carbon steel quenched in water.
