A process is described for producing amorphous metal alloys wherein impure ferrophosphorus slag, a by-product from a phosphorus-producing electric furnace, is used to supply phosphorus, chromium, vanadium and iron values to such alloys by mixing it with iron and any other desired metalloid and/or elements to form a molten mixture, treating the molten mixture to a separation step to remove insoluble slag formed in said molten mixture, and rapidly cooling the molten mixture to below its vitrification temperature to form a solid amorphous metal alloy.

Amorphous metal alloy and method of producing same

A process is described for producing amorphous metal alloys wherein impure ferrophosphorus slag, a by-product from a phosphorus-producing electric furnace, is used to supply phosphorus, chromium, vanadium and iron values to such alloys by treating the ferrophosphorus slag to a separation step to recover a purified molten ferrophos, mixing it with iron and any other desired metalloid and/or elements to form a molten mixture and rapidly cooling the molten mixture to below its vitrification temperature to form a solid amorphous metal alloy.

The invention provides an improved compact gas tungsten arc welding (GTAW) torch apparatus allows for welding on such surfaces that otherwise could not be welded with linear or 90.degree. bend welding torch apparatuses, by providing a bend greater than 282.degree.. The inventive torch is compact, not requiring a large radius of curvature or a water outlet pipe passing through the support housing. The inventive torch also uses one of the feed pipes as an electrical conductor.
