Abstract
An aspect of the present disclosure relates to an alloy composition, which may include 52 atomic percent to 68 atomic percent iron, 13 to 21 atomic percent nickel, 2 to 12 atomic percent cobalt, 10 to 19 atomic percent boron, optionally 1 to 5 atomic percent carbon, and optionally 0.3 to 16 atomic percent silicon. The alloy may include 5 to 95% by volume of one or more spinodal microconstituents, wherein the microconstituents exhibit a length scale less than 50 nm in a glass matrix.
