    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 the invention, a fuse comprises a reactive composite structure to interrupt the flow of current in a circuit. The term fuse, as used herein, is intended to cover current interrupters generically and thus encompasses fuses, circuit breakers and other devices for interrupting the flow of current through a conductor. Reactive composite structures comprise two or more phases of materials spaced in a controlled fashion throughout a composite in uniform layers, local layers, islands, or particles. Upon appropriate excitation, the materials undergo an exothermic chemical reaction that spreads rapidly through the composite structure generating heat and light. Moreover a reactive composite structure can break apart upon reaction. This breakage can rapidly interrupt the flow of current through the reactive composite structure. Such structures can provide high-speed current interruption. In addition, reactive composite structures can have abrupt reaction initiation thresholds such that a pulse of energy of a certain magnitude may initiate a clearing reaction but a slightly smaller pulse of energy may not. Such a reactive composite structure can thus provide a high speed, highly sensitive current interrupter.

    摘要： A multilayer structure has a selectable, (i) propagating reaction front velocity V, (ii) reaction initiation temperature attained by application of external energy and (iii) amount of energy delivered by a reaction of alternating unreacted layers of the multilayer structure. Because V is selectable and controllable, a variety of different applications for the multilayer structures are possible, including but not limited to their use as ignitors, in joining applications, in fabrication of new materials, as smart materials and in medical applications and devices. The multilayer structure has a period D, and an energy release rate constant K. Two or more alternating unreacted layers are made of different materials and separated by reacted zones. The period D is equal to a sum of the widths of each single alternating reaction layer of a particular material, and also includes a sum of reacted zone widths, t.sub.i, in the period D. The multilayer structure has a selectable propagating reaction front velocity V, whereV=K(1/D.sup.n).times.[1-(t.sub.i /D)]and n is about 0.8 to 1.2.
