Abstract

Directed to the production of composite copper-molybdenum sheet by assembling at least one plate of molybdenum with at least one plate of dispersion-strengthened copper to form a composite billet, heating the billet in a protective atmosphere to a temperature within the hot working range for copper, working the billet in a protective atmosphere to effect a reduction in thickness of at least about 40% to bond said dispersion-strengthened copper and said molybdenum together and thereafter further working the resulting bonded billet.
