Abstract
The L10-FePt nanocrystalline phase is directly formed by rapidly quenching the (Fe1-xPtx)77-78Zr 2-5B17-20 (x = 0.45-0.50) alloy melt. The as-quenched alloys exhibit coercivity higher than 200 kA/m. The in situ X-ray diffractometry at high temperatures reveals that the quenched L10-FePt phase in the alloys is stable up to the melting temperature. The L10-FePt phase forms directly without allowing the formation of the disordered face-centered cubic phase during rapid solidification.
