In some embodiments, the microcrystalline grains have an average grain size of less than or equal to 5 microns. In some embodiments, the metal alloy lacks long-range crystalline order among the microcrystalline grains. In some embodiments, the wire is used in a substrate used in the electrochemical cell. In some embodiments, the metal alloy is formed using a co-extrusion process comprising warming up the metallic alloy and applying pressure and simultaneously passing a core material through a die to obtain a composite structure.

  • Patent number: 8500925
    Abstract: The invention relates to a method for producing monotectic alloys with finely dispersed and homogeneously distributed second phase particles from two or more starting metals or alloys, in which the two or more metals or alloys are melted together or separately and the two or more, practically immiscible liquid metallic alloys are mixed to disperse the alloy of lower volume ratio with the other alloy of higher volume ratio, then the system is cooled below the eutectic temperature. The characteristic feature of the method is that at least one of the starting alloys contains stabilizing solid particles.
