Abstract Scope |
Minnealloy had been put forward as a candidate materials for the new soft magnetic materials in the application in electronic field because of its high saturation magnetization, low anisotropic energy and high electrical resistivity. We proposed a new method to synthesis the Minnealloy via preparing Fe-C melt spun as precursor for low temperature nitriding to improve the uniformity of the chemical composition and microstructure. The introduction of carbon into the iron as raw materials can form Fe16C2 which has a negative magneto crystalline anisotropy compared with the Fe16N2, while still holding the high Ms. Fe16N2, Fe16C2 or Fe16(CN) could be found either in the same grain or co-exist with each other as separate grains. Meanwhile, the electrical resistance is greatly improved compared with pure iron or low carbon steel, which makes this material as a good candidate for electronic applications. |
