Analysis of Minor Hysteresis Loops in Cold Rolled Low Carbon Steel

摘要: Minor hysteresis loops of cold rolled low carbon steel have been analyzed in connection with the rolling reduction. We found several simple relations between parameters minor and obtained minor-loop properties that are independent magnetic field amplitude field. The increase increasing reduction proportion to coercive force major loop. present analysis method using can be applied quantitative nondestructive evaluation dislocation density ferromagnetic materials
