摘要： A metallic glass-coated microwire has controllable surface porosity. The porosity is achieved by etching the metallic glass-coated microwire or other shapes of glass-coated bodies with acid after annealing to produce a multi-phase glass coating. Porous metallic glass-coated microwires are found to make superior PCR machines, which find use in a variety of in vivo, biochemical, and chemical sensors. Advantageously, the PCR apparatus is smaller, less expensive to construct than conventional units. It readily carries out in vivo passive or active operations.

摘要： A metallic glass-coated wire is formed by drawing a hollow glass fiber from a container in which molten alloy is entrained and solidified. Interference stresses extant between the glass coating and the alloy core of the wire are produced by systematically controlling thickness and mechanical elastic properties of the glass. The interference stress is tailored by selection of glass thickness and chemistry to optimize wire drawing process conditions, such as drawing temperature and strain rate. In addition, the interference stress is especially tailored to assure physical integrity of the glass-alloy composite wire product. Local property variations along the wire length are minimized, facilitating production of discrete wire segments especially suited for use in EAS applications.

摘要： A glass-coated amorphous metallic microwire is encoded with multi-bit digital information. Encoding is achieved magnetically, optically or through a combination of magnetic and optical encoding processes. Magnetic encoding is carried out by modifying the constituent magnetic domain structure through selective relief of interfacial stress between the glass coating and the amorphous metallic alloy core. It is also achieved by selective surface crystallization of the amorphous metallic core in order to produce a controlled magnetic bias field. Optical encoding is associated with the glass coating. It is readily achieved by fluorescent element deposition, patterned removal of fluorescent element coating, Bragg grating, and thermally activated pattern deposition. The magnetic and optical multi-bit encoding approaches for glass-coated amorphous metallic microwire can be used individually or collectively in either a redundant or a complementary manner. Encoded microwire of the instant invention can be assembled into tags for electronic article surveillance and into numerous other structures as well.

摘要： A drawn glass-coated metallic member has a thermal contraction coefficient differential such that the thermal contraction coefficient of the glass is less than that of the metallic member. The thermal contraction coefficient differential is maintained within a predetermined range during drawing. Drawn glass is placed under residual compression, interfacial bonding between said glass and said wire is substantially uniform, and surface cracking and bond breaks between metal and glass are substantially prevented. Optical properties of the glass coated microwire provide a basis for enabling multi-bit encoding capability. Advantageously data encoding is achieved optically, magneto-optically or using a combined magnetic and optical encoding mechanism. The duplex material constitution of the glass coated microwire permits imparting of data thereon by selection and processing of the glass. Data implantation is readily achieved in-line, during an initial drawing operation, or as a separate post-draw process. Reading of data on optically encoded glass coated microwire is readily accomplished by optical or magnetic methodology, or a combination thereof.

摘要： An apparatus and method for casting metal strip includes a moving chill body that has a quench surface. A nozzle mechanism deposits a stream of molten metal on a quenching region of the quench surface to form the strip. The nozzle mechanism has an exit portion with a nozzle orifice. A depletion mechanism includes a plurality of independently controllable gas nozzles to supply a reducing gas to multiple zones of a depletion region located adjacent to and upstream from the quenching region. The gas flow profile can be controlled in each zone independently of controlling the gas flow in other zones. The reducing gas reacts exothermically to lower the density to provide a low density reducing atmosphere within the depletion and substantially prevent formation of gas pockets in the strip.

摘要： An apparatus and method for permitting long-term continuous casting provides a plurality of orifices. By temporarily casting simultaneously from two adjacent orifices, it becomes possible to replace orifices without interrupting the casting process. Thus, the duration of continuous casting is not limited by the useful lifetime of a single casting orifice. Among the applications of the invention is the long-term continuous casting of metallic ribbon, such as amorphous metal ribbon.

摘要： A ferromagnetic amorphous metallic alloy strip is annealed to minimize exciting power rather than core loss. The strip has an exciting power less than 0.5 VA/kg when measured at 60 Hz and an operating induction of 1.40 to 1.45 Tesla, the measurement being carried out at ambient temperature. Cores composed of the strip can be run at higher operating induction than those annealed to minimize core loss. The physical size of the transformer's magnetic components, including the core, is significantly reduced.

摘要： Tin-based alloys that include micro-additions of certain elements avoid the discoloration that otherwise afflict those alloys when they are melted. The discoloration, which results from tin oxidation, correlates with poor performance of the alloys in filler metal applications. A preferred method of preparing the alloys of the invention is by rapid solidification from the melt.

摘要： A method and apparatus for casting rapidly solidified metallic strip includes a nozzle mechanism which has an orifice for directing a stream of molten metal onto a movable quench surface. An upstream constraint mechanism constrains an upstream portion of a melt puddle formed on the quench surface by molten metal from the molten metal stream. A side constraint mechanism constrains two, opposite side portions of the melt puddle, and a downstream constraint mechanism provides a selected gas pressure, constraining force against a downstream, top surface of the melt puddled.
