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
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.
