Abstract: A method for manufacturing a metal alloy component. The method comprises heating a shaped metal component and an alloying element source of vapor-phase transportable alloying element species in a reactor in the presence of a vapor-phase transport agent, wherein the heating is conducted under conditions which cause the vapor-phase transportable alloying element species to diffuse into the shaped metal component; and forming a metal alloy component alloyed with element species from the alloying element source.

Abstract: Methods of converting shaped templates into shaped metal-containing components, allowing for the production of freestanding, porous metal-containing replicas whose shapes and microstructures are derived from a shaped template, and partially or fully converting the shaped templates to produce metal-containing coatings on an underlying shaped template are described herein. Such coatings and replicas can be applied in a variety of fields including, but not limited to, catalysis, energy storage and conversion, and various structural or refractory materials and structural or refractory composite materials.
