Comparative study of structural and magnetic properties of ribbon and bulk Ni55Fe19Ga26 Heusler alloy
(Elsevier, 2021)
The influence of the fabrication method on the magnetostructural properties of a Ni55Fe19Ga26 Heusler alloy, obtained both as a ribbon, by melt-spinning, and as a pellet, by arc-melting, has been analyzed. It has ...

A Review of Different Models Derived from Classical Kolmogorov, Johnson and Mehl, and Avrami (KJMA) Theory to Recover Physical Meaning in Solid-State Transformations
(Wiley, 2022)
The classical theory of solid-state transformation based on nucleation and growth processes, developed by Kolmogorov, Johnson and Mehl, and Avrami (KJMA theory), is widely used in many different fields of research. In KJMA ...

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 ...
