1. A method for producing a final body comprising a fine-grained refractory complex concentrated alloy, wherein the fine-grained refractory complex concentrated alloy has an average grain size of 20 micrometers or less, the method comprising:
providing a precursor comprising one or more precursor compounds containing elements of the fine-grained refractory complex concentrated alloy;
reducing the one or more precursor compounds in the precursor via reaction with a reducing agent to generate the fine-grained refractory complex concentrated alloy and a compound comprising a product of the reaction between the reducing agent and the one or more precursor compounds;
generating a solid material that contains at least the fine-grained refractory complex concentrated alloy;
forming with the solid material a porous intermediate body comprising a pore volume; and
consolidating the porous intermediate body to partially or completely remove the pore volume from the porous intermediate body to yield with the porous intermediate body a film that is on a surface of the final body and has a lower porosity than the porous intermediate body, wherein:
the precursor is a precursor film;
the solid material generated by reducing the one or more precursor compounds in the precursor film is a fine-grained film; and
the porous intermediate body is an intermediate film formed with the fine-grained film.
