摘要
PROBLEM TO BE SOLVED: To provide a Sm-Fe-based alloy hardly oxidizing Sm, a Sm-Fe-N-based alloy and a rare earth magnet having the Sm-Fe-N-based alloy.;SOLUTION: A Sm-Fe-based alloy satisfies both of 0.9×β≤α≤1.8×β and 0α≤0.04, where α is the content of Al (mass%) and β is the content of oxygen (mass%), and the content of Sm is, by mass%, 25% to 26.5%. The Sm-Fe-based alloy can make difficult to oxidaze Sm and suppress the reduction of magnetic properties of a magnet.;COPYRIGHT: (C)2015,JPO&INPIT
