摘　　要：LaFeCoSi基合金中添加少量Cr、Ti元素,使其形成LaFe11.1-xCrxCo0.8Si1.1B0.25、LaFe11.1-xTixCo0.8Si1.1B0.25系列合金,利用磁热效应直接测量仪在1.5T的磁场下进行测量。实验结果表明:添加Cr、Ti元素都对材料的居里温度、磁热效应有影响,可利用这些合金元素在一定程度上调节材料的性能。LaFe11.1-xCrxCo0.8Si1.1B0.25 and LaFe11.1-xTixCo0.8Si1.1B0.25 series alloys were prepared by adding a small amount of Cr and Ti elements into LaFeCoSi-based alloy,and their magnetocaloric effects were measured using directly measuring instrument at 1.5T magnetic field.The experimental results show that both Cr addition and Ti addition have influence on Curie temperature and magnetocaloric effect of the serie alloy.The properties of the material can be adjusted to some extent taking advantage of these alloying elements.
