Abstract

Iron-chromium series amorphous alloys having excellent mechanical properties, high heat resistance and corrosion resistance consisting essentially of 1-40 atomic % of chromium, 7-35 atomic % of at least one of carbon, boron and phosphorus and the remainder being iron. In said amorphous alloys, a part of the content of iron may be substituted with at least one sub-component selected from the group consisting of nickel, cobalt, molybdenum, zirconium, titanium, manganese, vanadium, niobium, tungsten, tantalum and copper.
