The present invention relates to novel non-ferromagnetic amorphous steel alloys represented by the general formula: Fe—Mn-(Q)-B-M, wherein Q represents one or more elements selected from the group consisting of Sc, Y, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu, and M represents one or more elements selected from the group consisting of Cr, Co, Mo, C and Si. Typically the atomic percentage of the Q constituent is 10 or less. An aspect is to utilize these amorphous steels as coatings, rather than strictly bulk structural applications. In this fashion any structural metal alloy can be coated by various technologies by these alloys for protection from the environment. The resultant structures can utilize surface and bulk properties of the amorphous alloy.
An amorphous alloy represented by the formula:
An amorphous alloy represented by the formula:
An iron-based bulk-solidifying amorphous alloy comprising at least four elements including Fe, and having the formula Fe—Mn—Cr—Mo—(C, B)-Q, where Q is a large-atom element selected from the group consisting of Sc, Y, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, an amount of Mn is from 10 to 12 atomic %, an amount of chromium is from 0 to 16 atomic %, an amount of Mo is from 8 to 16 atomic %, an amount of (C, B) is greater than 18 atomic %, with an amount of C being at least 13 atomic % and an amount of B being at least 5 atomic %, and an amount of Q is greater than zero and less than or equal to 3 atomic %, and the bulk-solidifying amorphous alloy is non-ferromagnetic at ambient temperature.
