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.
