Nettet1. jan. 2013 · Several mechanisms of interphase precipitation have been proposed: (i) the ledge mechanism, when the growth of ferrite into austenite occurs by lateral movement of small ledges and, as a result ... 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.
