摘要
通过在LaFeCoSiB合金中添加微量金属元素Ni、V,制备了LaFe11.0NixCo0.8Si1.1B0.25(x=0.1),LaFe11.0VxCo0.8Si1.1B0.25(x=0.1,0.2)三组样品,测量了其绝热温变;实验结果表明,Ni、V不属于促进材料形成具有巨磁热效应相的物质,但有调节材料提高材料相变点的作用。
Three groups of samples of LaFel LaFe11.0NixCo0.8Si1.1B0.25(x=0.1),LaFe11.0VxCo0.8Si1.1B0.25(x=0.1,0.2), were prepared,and added trace elements Ni, V to LaFeCoSiB series alloys and adiabatic temperature change is measured. The the experimental results indicate that the elements added don' t belong to the materials promoting giant magnetocaloric effect. But these elements can adjust the phase changes of the materials.
