Abstract


A numerical model for the predictive assessment of laser transformation hardening of steels and other surface treatments both in metallic and non-metallic materials has been developed. Starting from material and geometry data, the problem of heat diffusion from the thermal source provided by the laser is solved with complete space and temperature-dependence. The developed 3D simulation model has been successfully checked against theoretical and experimental results both for metallic and non-metallic materials. Typical examples of its application have been the thermal surface hardening of steels and the analysis of thermal fields in low diffusivity materials (as optical glass) in laser polishing applications.
