Fe<sub>67.7</sub>Nb<sub>0.3</sub>Cr<sub>12</sub>B<sub>20</sub> glassy melt-spun ribbons and glass-coated microwires with T<sub>C</sub> around 310-320 K (~35-45°C) (the lowest ever reported for metallic glasses) have been prepared by rapid solidification. Excepting the thick melt-spun ribbons of 40 μm, all samples have a glassy structure in the as-quenched state, consisting of very small Fe-Cr and boride (Fe<sub>3</sub>B) clusters of sizes ranging from several nanometer up to several tens of… CONTINUE READING
