KINETICS OF ORDERING AND DISORDERING IN THE Fe-Al-Ti TERNARY ALLOY

摘要

The kinetics of ordering and disordering in the ternary b.c.c Fe-Al-Ti alloys is investigated by means of the micro-master equation method. It was found that there are transient ordered states in the ternary b.c.c Fe-Al-Ti alloy during the ordering from a quenched disordered state tot he equilibrium ordered state. Two different mechanisms account for the occurrence of the transient states. In the kinetics of disordering, the evolution of the order parameters shows fluctuations.
