The control of nanocrystal formation in amorphous alloys is particular importance for the development advanced nanocrystalline materials. In present study, authors succeeded controlling α-Fe and Nd2Fe14B nanocrystallization processes Nd9Fe85B6 by a combination severe plastic deformation at room temperature subsequent thermal annealing. α-Fe∕Nd2Fe14B nanocomposite magnets prepared this approach possess homogeneously distributed nanocrystals with small size, 15nm phase 26nm Nd2Fe14B, therefore...
A high number density (∼1023 m−3) of α-Fe nanocrystals with a size below 10 nm has been induced in amorphous Nd9Fe85B6 by high-pressure torsion deformation (HPTD) at room temperature. The subjected to HPTD presents quite different crystallization behavior as compared the nondeformed alloy. growth activation energies Eg=0.9 eV for and 0.5 Nd2Fe14B are determined from annealing time dependence their size. α-Fe/Nd2Fe14B nanocomposite magnets prepared combination subsequent thermal show enhanced...
The paper describes the influence of severe plastic deformation (SPD) on crystallization amorphous rapidly quenched Ti-Ni and Nd-Fe-B alloys. It has been revealed that SPD by high pressure torsion (HPT) at room temperature leads to formation nanocrystals in these initially subsequent annealing HPT-processed alloys homogeneous nanocrystalline structure. processing can be used as a novel method for producing bulk materials.
Abstract Magnetic properties and microstructure of high-energy (Nd,Dy)–Fe–B magnets with Dy no more than 1 wt % prepared via a low-oxygen routine are studied. Oxygen content in does not exceed 0.20 %. 0.5 %–Dy addition reliably stabilizes the coercivity M H c higher 13 kOe; this case, maximum energy density product ( BH ) max is 48.5–49.5 MG Oe. High magnetic hysteresis gained optimization chemical phase compositions magnets, as well their microstructure. The grain size main Nd 2 Fe 14 B...
