## Description

- description: To explore the impact of annealing temperature on the nucleation and
    subsequent growth of nanocrystalline α-Fe grains in a high saturation magnetization
    soft magnetic Fe84.8Si0.5B9.4P3.5Cu0.8C1.0 alloy, we conducted multiprobe analyses
    of the isothermal crystallization process within the 633 K to 733 K temperature
    range. Transmission electron microscopy and atom probe tomography observations
    for the samples isothermally annealed at 733 K and 633 K revealed distinct differences
    in microstructure. For the higher isothermal temperature, Cu clusters were larger,
    and α-Fe grains were finer. In contrast, for the lower isothermal temperature,
    Cu clusters were smaller, and α-Fe grains were coarser. Time-resolved synchrotron
    X-ray diffraction measurements provided a direct evidence of sporadic nucleation
    mechanism, highlighting the significant effect of isothermal temperature on the
    formation of α-Fe grains. To achieve an optimal microstructure for lower coercivity,
    it is crucial to control the Cu clustering and α-Fe nanocrystallization by annealing
    at higher temperatures for shorter durations.
