Abstract

In this work an attempt is made to study the impact of the quenching rate upon structure, hyperfine interactions, magnetic and mechanical properties of Fe₇₈Si₉B₁₃ metallic glasses. Other involved parameters in melt spinning method were kept invariant. Analytical techniques comprising X-ray diffraction, transmission Mössbauer spectrometry, vibration sample magnetometer, Vickers microhardness and differential scanning calorimetry were employed. Minor effect of quenching rate upon the macroscopic magnetic properties was detected. It was shown that notable changes in the local atomic arrangement, structure, and mechanical properties were unveiled, dominantly by represent the crystallization at the lowest quenching rate.

不同淬火速率对熔体旋压法制备Fe-Si-B非晶合金各项性能的影响

摘要

本工作试图研究淬火速率对Fe ₇₈ Si ₉ B ₁₃金属玻璃的结构、超精细相互作用、磁性和机械性能的影响。熔体纺丝方法中涉及的其他参数保持不变。采用的分析技术包括 X 射线衍射、透射穆斯堡尔光谱法、振动样品磁力计、维氏显微硬度和差示扫描量热法。检测到淬火速率对宏观磁性能的微小影响。结果表明，局部原子排列、结构和机械性能发生显着变化，主要是在最低淬火速率下结晶。
