The resultsshow that paying no enough attention to the time-dependent development of inter-face morphology will lead to evident overestimate of the solidification velocities atwhich the transitions of the planar-cellular and cellular-dendritic occur. A methodof finding the critical condition of interface instability by the asymptotic line ofV vs t_c curve is given from the experimental results. The effect of temperaturegradient on the cellular-dendritic transition rate has been determined.
