Mechanical Amorphization and Recrystallization of Mn-Co(Fe)-Ge(Si) Compositions
(MDPI, 2019-05)
Mechanical alloying using a planetary ball mill allowed us to obtain two homogeneous systems formed by units with nanometer size and MnCo0.8Fe0.2Ge1−xSix stoichiometry (x = 0 and 0.5). The phase evolution of the systems ...

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 ...

High Temperature Coercivity of Nb-containing HITPERM Alloys: Effect of Cu Addition
(Elsevier, 2008)
Hysteresis loops of nanocrystalline samples of Fe39Co39Nb6B16 - yCuy (y = 0, 1) HITPERM-type alloys were measured from room temperature up to 773K. The alloy with Cu shows a nearly constant value of coercivity (∼ 135A/m) ...
