Effects of Ti addition on the microstructure and magnetic properties of magnetostrictive Tb–Dy–Fe alloys

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)Fe3 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)Fe2 phase.
