摘要：

Alloys of Tb0.3Dy0.7Fe1.95-xTix were vacuum induction melted and investigated for microstructural features and magnetic properties. Ti addition aids in diminishing the formation of pro-peritectic (Dy, Tb)Fe-3 phase at the expense of TiFe2 phase formation. The magnetostriction was found to improve with the addition of Ti. Ti addition was also found to influence the saturation magnetization, Fe magnetic moment and Curie temperature of (Tb, Dy)Fe-2 phase. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd.
