Preferential Co Partitioning to α-Fe in Nanocrystalline CoFeNbB Alloys by Mn Addition
(Elsevier, 2009)
Influence of Mn addition on the microstructure and hyperfine parameters of amorphous and nanocrystalline Co60(FeMn)18Nb6B16 alloys has been studied. Although Mn addition does not yield significant differences in crystallization ...

Study of the Kinetics and Products of the Devitrification Process of Mechanically Amorphized Fe70Zr30 Alloy
(Elsevier, 2020)
Devitrification of mechanically alloyed amorphous Fe70Zr30 at. % compound consists on a two-step process: amorphous → amorphous + bcc Fe + Fe2Zr → Fe2Zr + Fe23Zr6. This sequence is inferred from the evolution of the Mössbauer ...

Effect of Pressure on the Phase Stability and Magnetostructural Transitions in Nickel-rich NiFeGa Ribbons
(Elsevier, 2020)
Ribbons of a Ni55Fe19Ga26 Heusler alloy were prepared by melt spinning technique. The effect of pressure on magnetostructural transitions was studied comparing as-spun ribbons to ribbons previously submitted to an axial ...
