Local determination of the field of induced magnetic anisotropy and the level of residual mechanical stresses in tensile-deformed bodies made of low-carbon steels

Resumo

A novel primary attachable transducer has been developed. The transducer makes it possible to estimate the level of residual mechanical stresses at local spots of articles that are made of lowcarbon steels. The critical fields of displacement of 90-degree domain boundaries have been determined experimentally by using a technique that allows one to separate contributions from two types of domain boundaries to the magnetization reversal by means of simultaneous action of two orthogonal magnetic fields. Optimum operating parameters of the primary transducer have been established.
