Magnetic Analysis of Recrystallization Processes during Annealing of Cold-Deformed Nickel
Source abstract
Abstract
Abstract We investigate changes in a complex of magnetic properties of cold-deformed and technically pure nickel with an increase in the annealing temperature. It is shown that the recovery leads to a monotone change in magnetic properties associated with the relaxation of internal stresses and a decrease in the dislocation density in deformed grains. It is established that the occurrence of recrystallized grains in the metal structure causes a change in the shape of the limit hysteresis loop of material and the occurrence of two peaks in the field dependence of the differential magnetic permeability on the descending and ascending loop branches. The change in the ratio of the volumes of deformed and recrystallized grains is reflected in the ratio of peaks. The completion of recrystallization again leads to a single peak in the field dependence of the differential permeability. The established patterns can be used to analyze nickel recrystallization processes.
