The L10-FePt nanocrystalline phase is directly formed by the rapid quenching of the (Fe0.55Pt0.45)-M-B (M = Zr, Nb and Ti) alloy melt. The as-quenched alloys exhibit coercivity higher than 200 kA/m. The direct formation of L10-FePt takes place at the compositional range where the equilibrium disordered fcc phase disappears by decreasing of melting temperature into the L10-FePt phase stable region with simultaneous addition of the M elements and B, presumably because of the strong interaction of Pt-M pairs.
