Abstract:
Crystal structure and magnetostrictive properties of Tb 0.2 Pr 0.8 (Fe 0.4 Co 0.6 ) 1.9 B x alloys have been investigated by means of x-ray diffraction and a standard strain technique. The matrix of Tb 0.2 Pr 0.8 (Fe 0.4 Co 0.6 ) 1.9 alloy consists of (Tb,Pr)(Fe,Co) 2 phase with a cubic MgCu 2 -type structure and some amount of (Tb,Pr)(Fe,Co) 3 phase with a PuNi 3 -type structure. The introduction of boron effectively restrains the emergence of the iron-rich phase, which can occupy either the substitutional or interstitial site in this alloy system. The single Laves phase can be obtained for the high Pr-content Tb 0.2 Pr 0.8 (Fe 0.4 Co 0.6 ) 1.9 B x alloys with 0.05 〈 x ≤0.15, which have improved magnetostrictive properties as compared to the boron free material.
