    摘要： In accordance with the invention, a first body is joined to a second body by joining a first amorphous braze layer to a surface of the first body and joining a second amorphous braze layer to a surface of the second body. A reactive multilayer foil is then disposed between the first and second amorphous braze layers. The layers are pressed together and the foil is ignited. Since the bodies can be joined to the braze layers by processes that do not require a furnace and the braze-coated bodies can be joined by the foil without a furnace, the method can produce strong brazed joints in typical workshop and field environments. Preferably the amorphous braze is a bulk metallic glass.

    摘要： In accordance with a preferred embodiment of the invention, an alloy or other composite material is provided formed of a bulk metallic glass matrix with a microstructure of crystalline metal particles. The alloy preferably has a composition of (XaNibCuc)100-d-eYdAlc, wherein the sum of a, b and c equals 100, wherein 40≦a≦80, 0≦b≦35, 0≦c≦40, 4≦d≦30, and 0≦e≦20, and wherein preferably X is composed of an early transition metal and preferably Y is composed of a refractory body-centered cubic early transition metal. A preferred embodiment of the invention also provides a method of producing an alloy composed of two or more phases at ambient temperature. The method includes the steps of providing a metastable crystalline phase composed of at least two elements, heating the metastable crystalline phase together with at least one additional element to form a liquid, casting the liquid, and cooling the liquid to form the alloy. In accordance with a preferred embodiment of the invention, the composition and cooling rate of the liquid can be controlled to determine the volume fraction of the crystalline phase and determine the size of the crystalline particles, respectively.
