A dynamic computational model developed within the context of the classical theory of phase evolution was applied to the W-C system to simulate the kinetics of phase selection during non-equilibrium solidification at 50%-C between the thermodynamically stable WC and the metastable WC 1Οͺx and W 2 C.
The kinetic effect, in combination with the effect of relaxation, was considered in the interface stability criterion under the non-equilibrium solidification. Employing a fresh mathematical derivation, a more general marginal stability criterion was obtained by incorporating the nonequilibrium kine
It is well-known that eutectics do not necessarily grow at the eutectic temperature, or with the eutectic composition. Thus, the eutectic point can be shifted due to non equilibrium conditions in the system. This fact was observed in many experiments. We try to explain this behaviour on the basis of
