| Abstract: | A series of low-carbon steel samples is investigated in the frame of a chain of magnetic non-destructive measurements on round robin samples, organized by the Universal Network for Magnetic Non-Destructive Evaluation. The samples have been plastically deformed by cold rolling to five consecutive stages of deformation. They are examined by the method of magnetic adaptive testing, typical by its low required magnetization of the samples. Results of the non-destructive magnetic tests are compared with the destructive mechanical measurements of Vickers hardness and ductile–brittle transition temperature. Linear, sensitive correlation is found between the magnetic parameters and the two mechanical ones. |
