摘要：
Transmission Mössbauer spectra were performed on FeZrB nanocrystalline alloys with high crystalline fraction (≈60%)at temperatures comprised within the range 77–600 K. We report the temperature dependencies of the magnetic hyperfine data of the three contributions: the crystalline bcc‐Fe grains, the residual amorphous phase, and the interface intermediate between the bulk of crystalline and amorphous phases. The evolution of the average value of the hyperfine field characteristic of the residual amorphous phase is discussed in terms of interactions between crystalline grains transmitting through the intergranular phase.
