A rapidly solidified Al85Y4Nd4Fe7 (%, in nominal atomic fraction) alloy was prepared by melt spinning. As-quenched and as-annealed microstructures were studied by differential scanning calorimetry (DSC), X-ray diffraction (XRD), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). Fully amorphous structure could be obtained in the rapidly solidified Al85Y4Nd4Fe7 alloy ribbons. The temperature of first crystallization exceeds 300 ℃. Crystallization of as-annealed Al85Y4Nd4Fe7 alloy is shown to occur in two stages: (1) primary crystallization of α-Al; (2) formation of Al3Y, Al13Fe4 and unknown crystalline phases.
