Abstract

The influence of Fe_72.5Cu₁Nb₂Mo_1.5Si₁₄B₉ nanocrystalline alloy annealing temperature on the structure and magnetic properties has been investigated. The heat treatment temperature of nanocrystalline soft magnetic alloy Fer_2.5Cu₁Nb₂ Mo_1.5Si₁₄B₉, which allows reaching the maximum value of the initial magnetic permeability, was found to be 15-20° higher than that ensuring the minimum coercive force. The relation between the numerical values of the coercive force, the initial magnetic permeability and the magnetic hysteresis loop rectangularity factor allows optimizing the mode of nanocrystalline alloy heat treatment.
