通过制备不同厚度的薄带，系统地研究了Ni-P二元合金非晶形成能力(GFA)与成分的关系，并测量了玻璃薄带的显微硬度。共晶合金Ni80.4P19.6在玻璃态下具有最好的GFA和最高的显微硬度。当合金成分偏离共晶成分时，GFA和显微硬度均降低，同时玻璃带X射线衍射谱的主宽峰半高宽增加。所有这些结果表明，金属玻璃的显微组织、GFA和显微硬度之间存在着密切的相关性。
The composition dependence of glass-forming ability (GFA) of Ni–P binary alloys was systematically examined by fabricating ribbons of different thicknesses, and the microhardness of the glassy ribbon was measured. The eutectic alloy Ni80.4P19.6has the best GFA and the highest microhardness in glassy state. As the alloy composition is deviated from the eutectic composition, both GFA and microhardness decrease, accompanied with an increasing full width at half maximum of the main broad peak in the X-ray diffraction spectrum of the glassy ribbon. All these results indicate a close correlation among microstructure, GFA and microhardness for the metallic glass.
