Amorphous alloys are materials that are produced by injecting heat and rapidly solidifying them. Since this material is cooled at an extremely fast rate of 10' to 6°C/SeC, it does not exhibit a crystalline structure and exhibits an amorphous state when the thickness falls below an appropriate thickness.

れている。Such materials are also obtained by containing about 20 at. % of non-metallic elements, compared to about 80 at. % for transition gold such as Fe, and are often ferromagnetic. It is known that amorphous alloys do not exhibit 5% crystalline magnetism because they do not have a crystalline structure, and also exhibit extremely high magnetic permeability and low core loss because they have high electrical resistance.

い温度まで結晶化し難いものが要望されていた。Such amorphous alloys can be said to be suitable mainly as magnetic materials, particularly as materials for transformers, motor cores, and the like. However, when amorphous alloys are used continuously and at temperatures much higher than room temperature, such as in transformers and motors,
1'? It changes to the most stable crystalline state with easy migration of molecules. The resulting crystalline state does not exhibit the excellent magnetic properties of an amorphous alloy. Therefore, no matter how good an amorphous alloy is, it is unstable to crystallization, and an amorphous alloy with a component composition that easily crystallizes is impractical. Therefore, there has been a demand for an amorphous alloy mainly composed of Iile, which is difficult to crystallize at high temperatures.
本発明の目的はこれらの安望にこた乏−１高い温度まで

。The attached drawing shows the relationship between Si and (13-1-C) when producing an amorphous alloy from the quaternary metals Fe, H, Si, and C, and the nearly horizontal line indicates the formation. The solid line indicates the maximum plate thickness, and the broken line indicates the crystalline alloy. The diagonal line indicates the crystallization temperature of the produced amorphous alloy. As can be seen from the accompanying drawings, the crystallization temperature varies depending on the value of 213+5i-1-C when C is small. Nonmetallic elements such as B, 8i, and C are 2n+5i-
)-C is limited to a range of 36 to 44% because
If it is less than 36% or more than 44%, it becomes difficult to form an amorphous alloy, so 2x+Y+z was limited to 36 to 44.
