Abstract:

Adopts the Enthalpy method to numerically simulate the temperature field of melting/solidification process in the surface layer of a stainless steel due to Nd:YAG pulsed laser treatment.With respect to the crystallization dynamics and rapid solidification theory, some essential parameters in relation to the microstructure evolution, such as solidification velocity, cooling speed and temperature gradient have been estimated and discussed

Key words: rapid melting and solidification in laser process, tefan problem, Enthalpy method, temperature field, microstructure evolution, stainless steel
