由快速凝固的Fe B合金制备的软磁材料由于纳米级α-铁晶粒在非晶基体中的结晶而表现出优异的软磁性能。已经提出，通过选择具有元素之间的负混合比的多原子合金化系统来降低临界凝固速率可以导致进一步的晶粒细化。在目前的工作中，合金与P，Ga和Al的添加，以满足降低临界凝固速率的规则生产。使用FESEM，辅以EDS、WDS和EBSD分析工具，详细研究了铸态和退火态合金的组织。此外，通过AES和XPS进行表面分析以确定相。版权所有© 2008约翰威利父子有限公司。
Soft magnetic materials derived from rapidly solidified FeSiB alloys exhibit excellent soft magnetic properties due to the crystallisation of nanoscale α‐iron grains in an amorphous matrix. It has been proposed that decreasing the critical solidification rate by choosing the multi‐atomic alloying system with negative enthalpies of mixing among elements can lead to further grain refinement. In the present work, an alloy with P, Ga and Al additions to satisfy the rule for decreasing the critical solidification rate was produced. The structures of as‐cast and annealed alloys were investigated in detail using FESEM, supplemented by EDS, WDS and EBSD analytical tools. Additionally, surface analysis by AES and XPS was performed to characterise the phases. Copyright © 2008 John Wiley & Sons, Ltd.
