Karkhin V. A., Okhapkin K. A. � Equivalent time estimation of the anisothermic diffusion processes in the heat-affected area at fusion welding

A technique for transforming an anisothermic diffusion problem (when the diffusion coefficient is not constant) into an isothermal problem (when the diffusion coefficient is constant) is proposed. It is based on the equivalent time concept. The interrelation between equivalent time and real time is established. The technique enables one to use known analytical solutions of linear diffusion problems. It is shown that preheating intensifies carbon diffusion in the heat � affected zone.
Key words: anisothermic diffusion process, diffusion coefficient, equivalent time, carbon
