Influence of Mn Content on the Microstructure and Hyperfine Interaction Parameters of Amorphous and Nanocrystalline Hitperm-Type FeCoMnNbB Alloys

摘要

Effects of Mn addition on the devitrification kinetics, microstructure and hyperfine interaction parameters of FeCoMnNbB alloys were investigated. As-cast and nanocrystalline samples were studied by different experimental techniques and results were correlated. Mn alloying provoked a significant lowering of the Curie temperature of the amorphous phase. No big changes were observed in the microstructure of the nanocrystalline alloys with the Mn addition.
