Abstract

1,127,221. Refining copper and copper alloys. RAYTHEON CO. Aug.27, 1965 [Sept. 29, 1964], No.36981/65. Headings C7A and C7D. Hydrogen embrittlement of copper, copper alloy or dispersion hardened copper is prevented by subjecting the metal to elemental boron vapour at a temperature between 800‹ C. and the melting point of the metal for a time sufficient to allow boron to diffuse into the solid metal lattice and react with any free oxygen therein. The metal may be exposed to boron vapour, packed in boron powder or painted with a mixture of boron powder and an inert binder. The resultant metal may contain up to 0À06% by weight of dissolved elemental boron and between 0.02 and 0.08%, or in the case of dispersion hardened copper up to 0.9%, boron oxide.
