%X Microstructure and subsequent phase transformations on heating of the melt-spun Nd85Al15 alloy have been studied by X-ray diffraction,transmission electron microscopy and differential scanning calorimetry.The melt-spun Nd85Al15 alloy shows two-stage transformation processes as follows:amorphous 72 nm supersaturated bcc-Nd(Al) solid solution→7 nm omega-like phase→AlNd3 hexagonal Nd.The activation energies for the first and second transformation were found to be 100kJ/mol and 188kJ/mol,respectively.The formation mechanism of nanoscale omega-like phase is discussed.
