メカニカルアロイングによる Fe-Fe₄N 粉末の構造と磁気的性質

抄録

We investigated formation of Fe-N solid solution by applying a mechanical alloying process to mixed powders of Fe and Fe₄N. Following the collapse of the fcc structure of Fe₄N at an early stage of mechanical milling, a product that has a bcc-like structure was formed. A certain amount of increase in magnetization was observed corresponding to the formation of this structure, although its value did not exceed that of iron.
