Uncharacteristic second order martensitic transformation in metals via epitaxial stress fields
Uncharacteristic second order martensitic transformation in metals via epitaxial stress fields
While most phase transformations, e.g., ferroelectric or ferromagnetic, can be first or second order depending on external applied fields, martensitic transformations in metallic alloys are nearly universally first order. We demonstrate that epitaxial stress originating from the incorporation of a tailored second phase can modify the free energy landscape that …
