ABSTRACT:
An improved mixture of alloy powders is provied for use in treating a preselected article alloy, for example, to repair or join multiple components of the article. The mixture has at least three distinct groups of alloy powders which together define a mixture composition range, with each alloy powder of the groups characterized by a composition and melting range different from the others and from the article alloy. In a preferred form, the mixture composition range comprises, by weight, 15-30% Cr, 1.5-6% W, 0.4-4% Al, 1-11% Ti, 1-6% Ta, up to 1.5% B, up to 0.5% Si, up to 0.2% Zr, up to 3% Mo, up to 0.3% Hf, up to 6% Cb, up to 2% Re, with the balance selected from Co and Ni along with incidental impurities.
