The peculiarities of the nanocrystallization process and copper addition effects for an amorphous Fe75.5Si13.5B9Cu2 alloy

Turning Ultra‐Low Coercivity and Ultra‐High Temperature Stability Within 897 K via Continuous Crystal Ordering Fluctuations

“…897 K is slightly higher than the highest temperature at which AN soft magnetic alloys do not precipitate Fe 2 B hard ferromagnet. [ 55 , 56 , 57 ] Figure 4b illustrates the M s / M s at 5 K‐ T / T c curve for the alloys in Figure 4a . The M s and i H c values of these soft magnetic alloys being compared at 897 K were obtained from commercial materials using the same test method with the same sample preparation conditions, and the room‐temperature ρ was taken from Ref.…”

Microstructures and Damping Properties in Ni-Al-Based Alloys

“…during heating [5][6]. When the oil-quenching temperature is low, the volume of formed L1 0 martensite is less and no apparent internal friction peak is produced during heating.…”

Structural, thermal and magnetic properties of Fe–Si–B–P–Cu melt-spun ribbons: Application of non-isothermal kinetics and the amorphous random anisotropy model

“…Variable cooling rates alter the diffusion process of atoms during the rapid solidification process and thus affect the degree of amorphicity [7] and local short-medium range order [8] in melt-spun ribbons. As a consequence, the thickness, microstructure and the microstructure-dependent properties of the melt-spun ribbons exhibit a strong dependence on quenching wheel speed [7][8][9][10][11][12].From the viewpoint of kinetics, the activation energies of the nucleation and growth of nanocrystallites, which determines the nanocrystallizaiton process and the microstructure of the annealed nanocrystalline alloy [13][14][15][16][17], are intimately related to the microstructure of the melt-spun alloys. Thermal analysis can give the activation energy of the crystallization process from the viewpoint of non-isothermal kinetics.…”
