Abstract: The invention improves the thermal conductivity of the material powder to be fired and also makes it possible to produce an amorphous magnetically soft body within a shortened period of time. The amorphous magnetically soft body is produced by preforming the material powder into a body first, and heating the preformed body without pressing. Stated more specifically, an amorphous magnetically soft body is produced from a material powder comprising a powder of an amorphous magnetically soft alloy, a glass having a softening point lower than the crystallization starting temperature of the alloy and a binding resin, by pressing the material powder in a preforming die to prepare a preformed body by the binding property of the resin, and firing the preformed body without pressing at a temperature higher than the softening point of the glass and lower than the crystallization starting temperature of the alloy to join the particles of the alloy with the glass.

Abstract: An alloy consisting essentially of, by weight, 0.1-0.6% C, up to 2.0% Si, 5.0-15.0% Mn, 5.0-15.0% Cr, 5.0-13.0% Ni, less than 1.0% V, and one or both of up to 1.0% Mo and up to 2.0% Nb, balance being substantially Fe and inevitable impurities. The alloy has outstanding nonmagnetic property, high hardness and good weldability, and particularly useful for electro-magnetic stirrer rolls in continuous casting machine.

Abstract: An alloy comprising, by weight, 0.1-0.6% C, up to 2% Si, 5-15% Mn, 5-15% Cr, 5-13% Ni, 1-3% V, and at least one of up to 1% Mo and up to 2% Nb, the balance being substantially Fe and inevitable impurities. The alloy has an outstanding non-magnetic property of up to about 1.004 in magnetic permeability and high hardness of above about 215 in Vickers hardness and is useful for electromagnetic stirrer rolls for continuous casting equipment.
