摘要
采用真空高频磁悬浮炉制备出一系列Gd3Al2-xSix(x=0,0.1,0.2,0.5,0.8)合金。通过Si对Al的部分替代,研究了Si元素微量替代对Gd3Al2合金磁热效应的影响。结果表明,Gd3Al2-xSix系合金的结构与Gd3Al2相同;随着Si含量的增加,Gd3Al2-xSix系合金的居里温度和磁热效应发生了变化,这说明Si对Al的部分替代改变了Gd3Al2合金的磁热效应。
A series of Gd3Al2-xSix（x=0, 0.1, 0.2, 0.5, 0.8） alloys were prepared in a high-frequency floating furnace. The effects of minor substitution of AI by Si on the magnetocaloric effects of Gd3Al2 alloy were investigated. The results show that the microstructure of Gd3Al2-xSix alloy is the same with Gd3A12 alloy. The Cure temperature and magnetocaloric effects of Gd3Al2-xSix alloys change with Si content increasing. The minor addition of Si can change the magnetocaloric effects of Gd3Al2-xSix alloy.
