    摘要： The present disclosure relates to a glass forming alloy. The glass forming alloy may include 43.0 atomic percent to 68.0 atomic percent iron, 10.0 atomic percent to 19.0 atomic percent boron, 13.0 atomic percent to 17.0 atomic percent nickel, 2.5 atomic percent to 21.0 atomic percent cobalt, optionally 0.1 atomic percent to 6.0 atomic percent carbon, and optionally 0.3 atomic percent to 3.5 atomic percent silicon. Furthermore, the glass forming alloy includes between 5% to 95% by volume one or more spinodal glass matrix microconstituents which include one or more semi-crystalline or crystalline phases at a length scale less than 50 nm in a glass matrix. In addition, the glass forming alloy is capable of blunting shear bands through localized deformation induced changes under tension.

    摘要： This application deals with glass forming iron based alloys which when produced as a metallic glass or mixed structure comprising metallic glass and nanocrystalline phases, results in extraordinary combinations of strength and ductility. Specifically, high strain up to 97% and high strength up to 5.9 GPa has been measured. Additionally, consistent with the amorphous structure high elasticity up to 2.6% has been observed. Thus, the new alloys developed result in structures and properties which yield high elasticity corresponding to a metallic glass, high plasticity corresponding to a ductile crystalline metal, and high strength as may be observed in nanoscale materials.
