摘要
概括了稀土元素在非晶合金中的主要作用,包括脱氧、净化合金液体、提高非晶形成能力、改善软磁性能等。阐述了金属钇、铈、铒、钕、钪等稀土元素分别在铁基、锆基、铝基和镁基等主要非晶合金体系中的应用情况。通过分析稀土元素的物理与化学特性,有助于合理选择和综合搭配稀土元素,改善非晶合金的性能。
The main function of rare earth in the amorphous alloy is briefly reviewed, including deoxidation, purifying the alloy liquid, increasing the glass forming ability and improving the soft magnetic property. It describes the action of Y, Ce, Er, Nd and Sc on the main amorphous alloy system, such as Fe-based, Zr-based, Abbased and Mg-based amorphous alloy. By analyzing the physical and chemical characteristics of rare earth elements, it can contribute to choose and integrate the different rare earth elements, as well as improve the performance of the amorphous alloy.
