The structure of γ-α 2 interfaces in binary and Ta-containing Ti-Al alloys was analysed by high-resolution transmission electron microscopy and image simulations. Growth of α 2-Ti 3 Al plates was found to be due to a ledge mechanism, consisting of Shockley partial dislocations on alternate (111) γ planes. The interface is atomically flat …

NettetDepending on the curvature of the MgIn 2 O 4 /MgO interface, the advancement of the interface proceeds either via a dislocation mechanism or via a ledge mechanism. Most probably, these two mechanisms result again in locally different growth rates, so that a feedback mechanism is established via the local micromorphology of the interface.
