Abstract

Bulk nanocrystalline Pr(Fe0.75Co0.15Cu0.01Nb0.04B0.05)1.93 alloys were synthesized by annealing its melt-spinning ribbons under different pressures and temperatures. It was demonstrated that the average grain size decreases with increasing pressure from 3 GPa to 6 GPa under the same annealing temperature of 853 K but increases with increasing temperature from 823 K to 923 K under the same annealing pressure of 6 GPa. A negative correlation between the coercivity and average grain size was found in the present investigated system. Grain refinement without losing the advantage of volume fraction of magnetostrictive phase offers the sample annealed under 6 GPa and 853 K the optimized magnetostrictive property, which might make it potential material for magnetostrictive application.
