Description
Summary:Melt spun ribbon samples of Fe 61Co 13.5Zr 1Pr 4.5− x Dy x B 20 ( x=0, 1) alloys of various thicknesses and suction cast 1 mm diameter rod and 1 and 3 mm outside diameter tube samples of the same alloy have been investigated. The nanocrystalline structure of the samples was derived by devitrification annealing at various temperatures for 30 min. Magnetic measurements revealed useful magnetic hardening and modest remanence enhancement for the (FeCo) 3RE 14B nanocrystalline structure.
