Abstracts

The ferromagnetic Fe-based amorphous alloys were studied due to properties for soft magnetic applications. Depending on different Nb addition, the formation of crystalline phases after annealing of amorphous Fe_{80-x}B₂₀Nb_{x} (x = 4,6,10) alloys was studied. The crystallization products as well as the phase structure were determined using the Mössbauer spectrometry combined with differential scanning calorimetry and magnetic measurements. The addition of Nb caused a shift of crystallization process towards higher temperatures and induced changes in coercive force and decreased the saturation magnetization. It was found that Nb addition changed the crystallization process from single crystallization for Fe₇₆B₂₀Nb₄ alloy to binary crystallization in the Fe₇₄B₂₀Nb₆ and Fe₇₀B₂₀Nb₁₀ glasses. The annealing process at the onset crystallization temperature induced complex phase formation including the α-Fe, Fe₃B, and Fe₂B phases for alloys x=4, 6.
