N2 - Determination of the mobilities for ordering transformation in Fe3Al has been attempted by comparing the rates of experimentally observed antiphase boundary (APB) migration with that simulated by a phase filed method (PFM). The simulated boundary mobility of D0 3-APB was sensitive to the ordering mobility. This allowed us to determine the ordering mobility for D0 3-LRO at 673 K to be 3 × 10 -11 m 3· J-1·s -1. However, the simulated boundary mobility of B2-APB was insensitive to the value of ordering mobility, and therefore the ordering mobility for B2-LRO could not be determined. The difference is ascribed to solutedrag which was quite significant at B2-APB.
