Investigation of the Evolution of Magnetic and Acoustic Characteristics as a Result of Annealing of Cold-Deformed Nickel

The change in the magnetic and acoustic properties of nickel as a result cold deformation subsequent annealing is investigated. It was found that leads to very significant changes nickel. coercive force decreases 50 times with an increase temperature 800 °C. Rayleigh coefficient, which characterizes mobility domain walls, monotonically increases by factor 20 over entire investigated range temperatures. greatest velocity damping longitudinal ultrasonic vibrations occur recrystallization shown diagnose structure magnitude residual stresses nickel, it advisable determine its parameters.
