Abstract

A method of forming an alloy composition including spinodal based glass matrix microconstituents. The method comprises melting an alloy composition comprising iron present in the range of 49 atomic percent (at %) to 65 at %, nickel present in the range of 10.0 at % to 16.5 at %, cobalt optionally present in the range of 0.1 at % to 12 at %, boron present in the range of 12.5 at % to 16.5 at %, silicon optionally present in the range of 0.1 at % to 8.0 at %, carbon optionally present in the range of 2 at % to 5 at %, chromium optionally present in the range of 2.5 at % to 13.35 at %, and niobium optionally present in the range of 1.5 at % to 2.5 at %, cooling the alloy composition at a rate of 103 K/s to 106 K/s.
