针对玻璃包覆非晶丝的内应力难以实验测量问题,提出了小角磁转法测量内应力的方法。内应力是在考虑其分布特点基础上通过测量磁弹性各向异性场而得出。采用该方法测量了不同退火温度下金属芯直径为46.5μm,玻璃皮厚度为8.7μm 的Fe45 Co20 Ni10 Si9 B16玻璃包覆非晶丝的内应力。结果表明,淬态下去除玻璃皮前的内应力为385MPa；460℃退火后去除玻璃皮前的内应力降低至120MPa,去除玻璃皮后内应力降低至27MPa。该测量方法的精度能够达到±7%,对玻璃包覆非晶丝的基础研究和技术应用都具有重要意义。
The small-angle magnetization rotation technique has been shown to be applicable for measuring the internal stress in glass-coated amorphous microwires that was difficult to determine experimentally.The inter-nal stress was obtained by measuring magnetoelastic anisotropy field while considering its distribution.The method was used to measure the internal stresses of Fe45 Co20 Ni10 Si9 B16 glass-coated amorphous microwires an-nealed at different temperature with metallic core diameter of 46.5μm and glass cover thickness of 8.7μm.The results showed that the internal stresses of as-prepared microwires with glass cover decreased from 385 to 120MPa after being annealed at 460℃,then to 27MPa after glass removal.The maximum experimental error of the measurement was estimated to be about ±7%.The obtained method was important for scientific researches and technological applications of glass-coated amorphous microwires.
