Abstract

Structure, Curie temperature and magnetostriction of RFex (1.6 less than or equal to x less than or equal to 2.0) and R(Fe1-yTiy)(1.8) (y less than or equal to 0.2) alloys (R = Dy0.65Tb0.25Pr0.1) have been investigated using optical microscopy, X-ray diffraction, AC initial susceptibility and standard strain gauge techniques. The homogenized RFe, alloys are found to be essentially single phase in the range of 1.8 less than or equal to x < 1.85. The second phase is a rare-earth-rich phase when x < 1.8, and (Dy, Tb, Pr)Fe-3 phase when x greater than or equal to 1.85. X-ray diffraction indicates that the R(Fe1-yTiy)(1.8) alloys contain a small amount of Fe2Ti phase when y greater than or equalto 0.05, which increases with the increment of Ti content. The Curie temperature of R(Fe1-yTiy)(1.8) alloys slightly enhances with increasing Ti concentration when y less than or equal to 0.05, then remains almost unchanged in the range of 0.05 < y less than or equal to 0.20. The magnetostriction of RFex alloys is improved when x less than or equal to 1.80 and reduced by increasing Fe content when x greater than or equal to 1.85. The magnetostriction of R(Fe1-yTiy)(1.8) alloys is lowered by increasing Ti content.
