Low-carbon steel samples deformed by cold rolling—analysis by the magnetic adaptive testing

Three series of samples of low-carbon steel were investigated by the method of magnetic adaptive testing (MAT). The samples were plastically deformed by cold rolling to five consecutive stages of deformation. Samples in one series were magnetically closed, those in the other two series were magnetically open. The presented results of MAT – typical by its low required magnetization of the samples – show highly sensitive and reliable correlation with plastic deformation and as a consequence also with mechanical embrittlement of the investigated material, regardless of the sample shape.
