• 要約等: Present authors have previously reported on the permanent magnet properties of iron-rich Fe-Pt alloys and a new Platiron magnet alloy (Fe-38.5 at%Pt) with a high energy product of 159 kJ·m<SUP>−3</SUP>. In this paper is further studied the effects of titanium, vanadium, rhodium, palladium, iridium, gold, aluminium, gallium and germanium on their magnetic properties, with the following results. The permanent magnet properties of Fe-Pt alloys can be improved by addition of a small amount of titanium and vanadium. Especially, the alloy containing 60 at% iron, 39 at% platinum and 1 at% titanium shows the highest maximum-energy-product of 165 kJ·m<SUP>−3</SUP>, coercive force of 360 kA·m<SUP>−1</SUP> and residual flux density of 1.0 T when aged at 823 K for 1.8 Ms after water-quenching. Further, the alloy containing 60.5 at% iron, 38.5 at% platinum and 1 at% vanadium shows the highest coercive force of 410 kA·m<SUP>−1</SUP>, maximum energy product of 160 kJ·m<SUP>−3</SUP> and residual flux density of 1.04 T when aged at 773 K for 252 ks after water-quenching. But, in the cases of other elements additions, the permanent magnet properties can not be remarkably improved.<BR>It is presumed that the excellent permanent magnet properties of the Platiron magnet alloys are related to the microstructure of γ<SUB>1</SUB> order phase with the L1<SUB>0</SUB>-type and its high magnetocrystalline anisotropy.
