AbstractThe nucleation stage of the L12→DO19 transformation in Fe3Ge has been studied by in-situ heating experiments in the TEM. Stacking faults, which were identified as embryos of the product DO19 phase, were observed to generate from sources such as twin boundaries and superdislocations by the formation of stairrod dislocations. Two types of stair-rod dislocations were identified and these had overall Burgers vector content of a perfect screw dislocation and zero, respectively. Thickening was via a stacking fault overlapping process. © 1997 Elsevier Science Limited.
