Paper Title:
Structure and Magnetostrictive Properties of Tb0.2Pr0.8(Fe0.4Co0.6)1.9Bx Alloys
  Abstract

Crystal structure and magnetostrictive properties of Tb0.2Pr0.8(Fe0.4Co0.6)1.9Bx alloys have been investigated by means of x-ray diffraction and a standard strain technique. The matrix of Tb0.2Pr0.8(Fe0.4Co0.6)1.9 alloy consists of (Tb,Pr)(Fe,Co)2 phase with a cubic MgCu2-type structure and some amount of (Tb,Pr)(Fe,Co)3 phase with a PuNi3-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 Tb0.2Pr0.8(Fe0.4Co0.6)1.9Bx alloys with 0.05< x ≤0.15, which have improved magnetostrictive properties as compared to the boron free material.
