摘要： An amorphous metal alloy strip is disclosed having a width greater than about one inch and a thickness less than about 0.003 inch, this alloy consists essentially of 77 to 80 atomic percent iron, 12 to 16 atomic percent boron and 5 to 10 atomic percent silicon with incidental impurities. The strip has a 60 cycle per second core loss of less than about 0.100 watts per pound at 12.6 kilogauss, saturation magnetization of at least 15 kilogauss, and a coercive force of less than about 0.04 oersteds. Such alloy is further characterized by increased castability and the strip produced therefrom exhibits at least singular ductility. A method of producing such optimum strip is also disclosed.

摘要： A ferritic stainless steel alloy is provided which is hot workable and is resistant to thermal cyclic oxidation and scaling at elevated temperatures. The iron-chromium-aluminum alloy contains cerium, lanthanum and other rare earths and is suitable for forming thereon an adherent textured aluminum oxide surface. Also provided are an oxidation resistant catalytic substrate made from the alloy and a method of making the steel article and products having a textured aluminum oxide surface. The method includes steps of heat treating the cold worked steel article to form the adherent textured oxide surface and, optionally, pretreatment heating of the cold worked article before the texture heat treatment.
