Abstract

The influence of varying annealing temperature on magnetic and magnetoacoustic properties of cold-deformed alloy 97% Ni, 3% Fe has been investigated. The study of the microstructure of the nickel–iron alloy showed the presence of rolling texture up to annealing temperatures of approximately 500°C. With further increase of annealing temperature of the investigated alloy, as a result of recrystallization, the texture disappears and anisotropy of its magnetic and magnetoacoustic parameters decreases considerably. The sensitivities of magnetic and magnetoacoustic parameters to the rolling-induced anisotropy of the nickel–iron alloy are compared. It is shown that the differential magnetic permeability measured with the DIUS-1.21M hardware and software system is a parameter most sensitive to anisotropy.
