  • Abstract
    These experiments were carried out to investigate the effects of the composition and annealing conditions on the magnetic properties of isotropic cast (Pr, Dy)-(Fe, Co)-(B, C) alloys. Compositions were Pr15Fe77B8, Pr15(Fe0.9Co0.1)77(B1-xCx)8, and (Pr0.9Dy0.05)15(Fe0.9-Co0.1)77(B0.5C0.5)8, In Pr15(Fe0.9Co0.1)77(B1-xCx)8 alloys, the value of HCJ increased with increasing carbon substitution in the range x=0 to 0.5. Of these cast alloys, (Pr0.95Dy0.05)15(Fe0.9Co0.1)77 (B0.5Co0.5)8 alloy annealed for 5 hours at 800°C exhibited the best magnetic properties, with (BH)max=38.4 kJ/m3, HCJ=392 kA/m, HCB=248 kA/m and Br=0.54 T. EDX analysis revealed that this alloys consists of two phases: a (Pr,Dy)-rich phase, and a (Pr,Dy)2(Fe,Co)14(B,C) phase.
