Abstract
The magnetostrictive properties and microstructure of Tb0.27Dy0.73Fe2Bx (x=0, 0.05, 0.1, 0.15, 0.2) have been investigated. Measurement of magnetic properties, X-ray diffraction and magnetostriction were made on Tb0.27Dy0.73Fe2Bx polycrystalline samples prepared by arc melting. With the increase of boron content x, the iron-rich phase which leads to the detriment of magnetostrictive properties, decreases. The matrix phase of these alloys also has the MgCu2 structure. The lattice constant and Curie transition temperature change only slightly. The doping of boron in the Tb0.27Dy0.73Fe2 alloy can restrain the emergence of the iron-rich phase. The peritectic region probably shifts slightly with the addition of boron.
