The aim of this work was to investigate the features of microstructure, phase composition, mechanical properties, and thermal stability of the two-component melt-spun Ni55Fe20Cu5P10B10 alloy. The development of the microstructure after heating to elevated temperatures was studied using scanning electron microscope and in situ high temperature X-ray diffraction. The high-temperature behavior of the two-component melt-spun Ni55Fe20Cu5P10B10 alloy and Ni40Fe40B20, Ni70Cu10P20, and Ni55Fe20Cu5P10B10 alloys melt-spun from single-chamber crucible was investigated using differential scanning calorymetry at different heating rates and by dynamic mechanical thermal analysis. The results show that band-like microstructure of the composite alloy is stable even at 800 K, although coarsening of bands forming the microstructure of the ribbons is observed above 550 K. Plastic deformation is observed in the composite previously heated to temperatures of 600-650 K. The properties of the composite alloy are generally different than the properties obtained for the melt-spun alloy of the same average nominal composition produced traditionally. Additionally, the mechanical and the thermal properties in this composite are inherited from the amorphous state of alloys that are precursors for two-component melt spinning (TCMS) processing.
这项工作的目的是研究双组分熔体纺丝Ni55Fe20Cu5P10B10合金的微观结构、相组成、力学性能和热稳定性特征。使用扫描电子显微镜和原位高温X射线衍射研究了加热到高温后微观结构的演变。使用差示扫描量热法在不同加热速率下并通过动态力学热分析研究了从单室坩埚熔体纺丝的双组分熔体纺丝Ni55Fe20Cu5P10B10合金以及Ni40Fe40B20、Ni70Cu10P20和Ni55Fe20Cu5P10B10合金的高温行为。结果表明，复合合金的带状微观结构即使在800 K时也是稳定的，尽管在550 K以上观察到形成薄带微观结构的条带变粗。在先前加热到600 - 650 K温度的复合材料中观察到塑性变形。复合合金的性能通常不同于传统生产的具有相同平均标称成分的熔体纺丝合金所获得的性能。此外，该复合材料的力学和热性能继承自作为双组分熔体纺丝（TCMS）加工前驱体的合金的非晶态。
