Kinetics of ordering and disordering in the Fe–Al–Ti ternary alloy Original Research Article

The kinetics of ordering and disordering in the ternary b.c.c. Fe–Al–Ti alloy 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 to the 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.
