A process for producing iron, phosphorus, carbon and chromium based amorphous metal alloys of the type in which a metal alloy in the liquid phase is cooled very rapidly to obtain a vitreous structure, wherein the liquid phase is prepared from cast iron, phosphorus and chromium. This process provides a low cost amorphous alloy as compared to that of crystalline products, and one which, however, possesses improved properties. The invention also relates to the amorphous alloy obtained having the following composition by atomic percentage: Cr: 1.5 to 8; C: 8 to 16; P: 4 to 12; Si: up to 3.5; the remainder being iron and the P/C ratio being less than 1.
A process for the production of an iron-based amorphous metal alloy containing phosphorus, carbon, chromium, and iron comprising:
The process of any one of the preceding claims, wherein the cast iron used is a cleaned cast iron directly obtained during high furnace casting which has undergone no prior treatment.
An iron-based amorphous metal alloy of the type containing iron, phosphorus, carbon and chromium having the following composition by atomic percentage:
