Ti的添加量对磁致伸缩性能的影响很大, 当x=0.03时, Ti的添加使磁致伸缩性能较 Tb0.3Dy0.7Fe1.95母合金提高幅度最大, 但当x=0.09时, 由于顺磁相TiFe2和富(R, Ti)相的析出对磁致伸缩性能不利, 但相对于Tb0.3Dy0.7Fe1.95母合金也有少量提高. 关键词 ： Tb-Dy-Fe合金,  磁致伸缩,  Ti添加,  显微组织,  Laves相     Abstract：The Tb0.3Dy0.7Fe1.95-xTix ($x$=0, 0.03, 0.06, 0.09) alloys were prepared by high--vacuum non-consumable arc melting furnace. The crystal structure, microstructure, magnetostriction and their relationships of the Tb0.3Dy0.7Fe1.95-xTix ($x$=0, 0.03, 0.06, 0.09) alloys were systematically studied. The results demonstrated that the matrix phase of the Tb0.3Dy0.7Fe1.95-xTix (x=0.03, 0.06, 0.09) alloys consisted predominantly of the Laves phase with MgCu2 structure. After Ti addition, the lattice parameter of the Laves phase in the alloys was decreased by substituting rare earth elements Tb and Dy, and the formation of the TiFe2 phase as the primary phase made the solidifying liquid become rich in rare earths and suppressed the formation of the deleterious RFe3 (R=Tb and Dy) phase. Ti was found to be soluble in the matrix RFe2 and R-rich phases and formed the matrix (R, Ti)Fe2 and (R, Ti)-rich phases. The concentration of Ti affected the magnetostriction significantly. The improvement in magnetostriction was maximum for the Ti-added alloys with a low concentration of the Ti (x=0.03) as compared to the parent alloy Tb0.3Dy0.7Fe1.95. However, the decrease in magnetostriction at a higher concentration (x=0.09) was due to the formation of paramagnetic phases TiFe2 and (R, Ti)-rich. Whereas the magnetostriction had little improvement as compared to the parent alloy\linebreak Tb0.3Dy0.7Fe1.95.
