Tough iron-based bulk metallic glass alloys |
摘要 |
A family of iron-based, phosphor-containing bulk metallic glasses having excellent processibility and toughness, methods for forming such alloys, and processes for manufacturing articles therefrom are provided. The inventive iron-based alloy is based on the observation that by very tightly controlling the composition of the metalloid moiety of the Fe-based, P-containing bulk metallic glass alloys it is possible to obtain highly processable alloys with surprisingly low shear modulus and high toughness. |

1. An Fe-based metallic glass composition comprising at least Fe, Mo, P, C and B, where Fe comprises an atomic percent of at least 60, Mo comprises an atomic percent of from 2 to 8, P comprises an atomic percent of from 5 to 17.5, C comprises an atomic percent of from 3 to 6.5, and B comprises an atomic percent of from 1 to 3.5, wherein the alloy has a shear modulus (G) of less than 60 GPa, and the composition is capable of forming a bulk object having a critical thickness of at least 2 mm. |
