摘 要：<正>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.
