The mixture model of Al85Y4Nd4Ni7 alloy in which a partially crystallized amorphous alloy is regarded as a nanocomposite of an Al nanoparticle and a remaining amorphous matrix is presented. Its evolution in the process of crystallization has been investigated by differential scanning calorimetry (DSC), X-ray diffraction (XRD), and transmission electron microscopy (TEM). Mainly amorphous structure with α-Al nanocrystals embedded in the amorphous matrix has been revealed by melt spirting the alloy. Crystallization is showed to occur in three stages: (1) crystallization of amorphous alloy and formation of AlNiY, AlNdNi and unknown crystalline phases, (2) formation of A13Y and Al3Nd, and (3) formation of Al3Ni.
