导言 急冷非晶合金具有很高的内应力原子排列为亚稳态,当去应力退火时非晶态相逐步发生转变,经过一系列亚稳态相,最终转变成完全稳定的结晶相,非晶态合金的许多重要物理性能都随结构弛豫和结晶化过程而变化。高磁感铁硅硼非晶薄带是作为工频变压器铁芯或高频变换器最合适的铁磁非晶态材料。它的重要的技术磁化参数如激磁功率、铁芯损耗以及磁导率等都受低温转变行为影
Introduction Quenched amorphous alloys have a high internal stress. The atoms are arranged in a metastable state. When the stress-relieving annealing occurs, the amorphous phase changes step by step. After a series of metastable phases, it eventually turns into a completely stable crystalline phase, Many of the important physical properties of state alloys vary with the structure relaxation and crystallization processes. High magnetic induction Si-B amorphous ribbon as the power frequency transformer core or high-frequency converter is the most suitable ferromagnetic amorphous material. Its important technical magnetization parameters such as excitation power, core loss and permeability are affected by low temperature transition behavior
