摘要：
A large kinetics hysteresis is found to exist between the forward and backward reactions of the L1(2) <-> DO19 transformation in Fe3Ge. The slow DO19 to L1(2) transformation leaves behind very stable twins and stacking fault debris. In-situ annealing experiments in the transmission electron microscope revealed that nucleation for the reverse L1(2) to DO19 reaction takes place efficiently at these defects.
