Simulation of processes of carbon heat-and-mass transfer in pulsed laser exposure range in alloys with austenitic structure

The mathematical model for description of the processes of heat-and-mass transfer un- der the pulsed laser exposure is proposed. It consists of heat and diffusion problems taking into consideration the nonlinear dependence of the carbon diffusion coefficient on temperature and concentration. In co...
