A multimetallic article of manufacture comprising a body (40) of a first metallic material with discrete regions (65) therein of a second metallic material is manufactured by the in situ alloying of a third material with the first material. The alloying is performed by depositing the third material at locations on the body where the first material is melted by an energy beam (45) such as a carbon dioxide laser or electron beam.
