Abstract: A method is provided for producing substantially austenitic stainless steel strip, particularly chromium-nickel grades, having ultra low sulfur levels up to 0.002% by conventionally continuously casting the slab and thereafter hot rolling the slab to hot-rolled band by improving the ability to achieve hot-rolled band having good surface quality as characterized by reduced metallurgical slivers.

Abstract: Nitrogen-containing amorphous alloys having a combination of superior properties which are highly valuable and desirable for ferromagnetic materials or superconducting materials are produced by sputtering metallic materials and nitrogen compounds containing semi-metal or semiconducting metal, such as boron or silicon, without requiring the use of nitrogen gas. The produced alloy has a novel structure, represented by the formula:MxLyNz(wherein M is at least one metal or alloy; L is at least one semimetal or semiconducting element; and x, y and z are fractional atomic percentages totaling 100 (i.e., x+y+z=100) and the value of y+z being 10 or more and the respective values of x, y, z being not zero).

Abstract: Amorphous alloys containing zirconium as an amorphous forming metal and having teh formula X.sub..alpha. Z.sub..gamma. wherein X is at least one of Fe, Co and Ni, .alpha. is 80 to 92 atomic %, Z is zirconium, .gamma. is 8 to 20 atomic % and the sum of .alpha. and .gamma. is 100 atomic %, cause little variation of properties during aging and embrittlement because they contain no metalloid as the amorphous forming element, and they further have excellent strength, hardness, corrosion resistance and heat resistance and maintain superior magnetic properties which are characteristic of iron group elements.
