Abstract

High resolution electron microscopy was used to study a martensitic interface in a Y2O3-stabilized ZrO2 alloy. The interface was found to be dislocated; the dislocations have a component along <111> t and are spaced ~14 (111) t planes. These dislocations are believed to be misfit or interface dislocations, present to relieve strains at the t/m interface. This interface thus cannot be the invariant plane strain interface calculated by the crystallographic theories of martensitic transformations.
