ABSTRACT:
A method for bonding aluminum and aluminum alloys to refractory materials. A body of metal is heated to an elevated temperature at a total pressure above the vapor pressure of aluminum but less than atmospheric pressure. Oxygen partial pressure is maintained sufficiently low to prevent substantial oxidation of the metal. The heated body is contacted with a mass of refractory material and cooled, thereby forming a composite.
