ALLOY COMPOSITION, NANOCRYSTALLINE Fe ALLOY, AND PREPARATION METHOD THEREFOR |
| 摘要 |
An alloy composition of Fe (100-X-Y-Z) B X P Y Cu z , where 4 ‰¤ X ‰¤ 14 atomic %, 0 < Y ‰¤ 10 atomic %, and 0.5 ‰¤ Z ‰¤ 2 atomic %. This alloy composition has an amorphous phase as a main phase. This alloy composition is used as a starting material and exposed to a heat-treatment so that nanocrystals comprising no more than 25 nm of bccFe can be crystallized. Thus, an Fe-based nano-crystalline alloy having superior magnetic properties can be obtained. |
