Abstract: Brazing of metal parts employing a thin, homogeneous, ductile, filler metal foil is disclosed. The brazing foil, useful for brazing stainless steels, is less than about 0.0025 inch thick and has a composition consisting essentially of 0 to about 4 atom percent iron, 0 to about 21 atom percent chromium, 0 to about 19 atom percent boron, 0 to about 12 atom percent silicon, 0 to about 22 atom percent phosphorus and the balance nickel and incidental impurities. In addition to containing the foregoing elements within the above-noted composition ranges, the composition must be such that the total of iron, chromium and nickel ranges from about 76 to 84 atom percent and the total of boron, silicon and phosphorus ranges from about 16 to 24 atom percent. The ductile foil permits fabrication of preforms of complex shapes which do not require binders and/or fluxes necessary for brazing powders presently used to braze stainless steels and nickel base alloys.

Abstract: An amorphous metal alloy which is at least 90 percent amorphous and consists essentially of a composition having the formula Fe.sub.a B.sub.b Si.sub.c C.sub.d wherein "a", "b", "c" and "d" are atomic percentages ranging from about 80.0 to 82.0, 12.5 to 14.5, 2.5 to 5.0 and 1.5 to 2.5, respectively, with the proviso that the sum of "a", "b", "c" and "d" equals 100, is annealed at a temperature ranging from 380.degree.-410.degree. C. The resulting alloy has decreased high frequency core losses and increased low field permeability; is particularly suited for high frequency applications.

Abstract: Brazing of metal parts employing a homogeneous, ductile, filler metal foil is disclosed. The brazing foil, useful for brazing cobalt based alloys, has a composition consisting essentially of 0 to about 4 atom percent iron, 0 to about 26 atom percent chromium, 0 to about 20 atom percent nickel, 0 to about 4 atom percent tungsten, 0 to about 4 atom percent molybdenum, 0 to about 20 atom percent boron, 0 to about 12 atom percent silicon, 0 to about 2 atom percent carbon and the balance essentially cobalt and incidental impurities. In addition to containing the foregoing elements within the above-noted composition ranges, the composition must be such that the total of iron, chromium, nickel, tungsten, molybdenum and cobalt ranges from about 75 to 85 atom percent and the total of boron, silicon and carbon ranges from about 15 to 25 atom percent.

Abstract: Novel glassy metal alloys and the brazing of metal parts employing a homogeneous ductile filler metal foil of these alloys is disclosed. The glassy metal alloys have a composition consisting essentially of 5 to 40 atom percent nickel, 15 to 20 atom percent phosphorus with the balance being copper and incidental impurities. These alloys can be produced in the form of foil useful for brazing metal articles, particularly articles composed of copper and copper alloys.

Abstract: An amorphous metal alloy which is at least 90% amorphous having enhanced magnetic properties and consisting essentially of a composition having the formula Fe.sub.a B.sub.b Si.sub.c C.sub.d wherein "a", "b", "c" and "d" are atomic percentages ranging from about 80.0 to 82.0, 12.5 to 14.5, 2.5 to 5.0 and 1.5 to 2.5, respectively, with the proviso that the sum of "a", "b", "c" and "d" equals 100.
