An analysis of the first order transition kinetics between D0&sub(3) and L1&sub(2) phases in Fe&sub(3)Ga-type alloy is carried out. Structure and magnetostriction of the samples were carefully controlled by SEM-EBSD analysis and magnetostriction tests after different heat treatments, and additionally in in situ regime by VSM and DSC. C-shaped curves for time-temperature-transition (TTT) diagram based on the results of the EBSD analysis of Fe-27Ga alloy are constructed in the temperature range between 400 and 550 &sup(o)C. TTT diagram shows that the nucleation rate for L1&sub(2) phase increases in the sequence 400 *> 475 *> 550 &sup(o)C, while the growth rate reaches a maximum at about 500–525 &sup(o)C. Effect of D0&sub(3) *<*> L1&sub(2) thermocycling on the kinetic of the D0&sub(3) *<*> L1&sub(2) transition is studied for the first time. The amount of the L1&sub(2) phase after sample re-quenching and subsequent annealing at the same annealing temperature and time, significantly increases compared with the first cycle quenching and subsequent annealing, demonstrating memory effect of previous transitions.
