Abstract

Computer simulations of the phenomenon of contact melting in binary alloys with chemical miscibility gap are performed on the basis of the phase field theory. Kinetics of the process is examined within the isothermal approximation, as a function of initial state. As evidenced by simulations, the simplest phase field model is capable of reproducing the basic properties of the phenomenon. The numerical results obtained suggest the diffusive nature of contact melting.
