  • Patent number: 10563275
    Abstract: A method and apparatus are described for creation of amorphous metals using electromagnetic supercooling of a metal/alloy without the utilization of rapid quenching or immaculate process environments. By exposing the cooling melt to electric currents, either induced by an alternating current (AC) magnetic field or supplied directly, crystallization is suppressed, and the melt can reach significant levels of supercooling. With sufficient current densities in the melt, the supercooling can extend all the way into the glass transition range for certain materials, at which point an amorphous metal/alloy is created.
