Utilization of carbon dioxide and/or carbon monoxide gases in processing metallic glass compositions

摘要

A method of forming an iron based glass forming alloy. The method may include providing a feedstock of an iron based glass forming alloy, melting the feedstock, casting the feedstock into an elongated body in an environment comprising 50% or more of a gas selected from carbon dioxide, carbon monoxide or mixtures thereof.

1. A method of forming an iron based glass forming alloy, comprising:
providing a feedstock of an iron based glass forming alloy, wherein said iron based glass forming alloy comprises 40.5 to 65.5 atomic percent iron, 13.0 to 17.5 atomic percent nickel, 2.0 to 21.5 atomic percent cobalt, 11.5 to 17.0 atomic percent boron, optionally 4.0 to 8.0 atomic percent carbon, optionally 0.3 to 4.5 atomic percent silicon, and optionally 2.0 to 20.5 atomic percent chromium; melting said feedstock; casting said feedstock into an elongated body in an environment comprising an inert gas and 50% or more of a gas selected from carbon dioxide, carbon monoxide or mixtures thereof, wherein said gasses are present at a pressure of 0.1 atm to 0.67 atm, and said iron based glass forming alloy after casting exhibits an ultimate tensile strength in the range of 1.55 GPa to 3.30 GPa and a Young's Modulus in the range of 103.7 GPa to 230.7 GPa.
