Abstract

A significant improvement in the soft magnetic properties of Fe-based amorphous alloys can be achieved through high-temperature annealing, which effectively reduces residual stresses. However, annealing-induced structural relaxation depletes free volume in the amorphous alloy, leading to a significant reduction in toughness. In this work, we investigated the effect of ribbon width on transverse thickness uniformity in industrial Fe-based amorphous ribbons. To this end, we developed a simple and viable annealing strategy for low-temperature magnetic stabilization. This strategy maintains the toughness of the annealed ribbons at a level comparable to the as-quenched state. Additionally, the magnetic cores fabricated from these ribbons exhibit extremely low coercivity fluctuation. These findings provide a guiding heat treatment process for the application of Fe-based amorphous alloys in high-frequency motors.

工业铁基非晶合金低温退火后的磁稳定性和优异的延展性

通过高温退火可以显著改善铁基非晶合金的软磁性能，有效地降低了残余应力。然而，退火引起的结构松弛耗尽了非晶合金的自由体积，导致韧性显著降低。在本工作中，我们研究了带宽度对工业铁基非晶带横向厚度均匀性的影响。为此，我们开发了一种简单可行的低温磁稳定退火策略。这种策略使退火带的韧性保持在与淬火状态相当的水平上。此外，由这些磁带制成的磁芯表现出极低的矫顽力波动。这些研究结果为铁基非晶合金在高频电机中的应用提供了一种指导性的热处理工艺。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
