Abstract
With a specially designed sensor and testing system, a study was made on the changing pattern of the magnetic induction sensitivity signal i nduced by magnetic anisotropy during the fatigue processing of carbon steel. It was found that signal change has several characteristic stag es and obvious extreme points. The points coincided with the position of the fatigue strain peaks. The signal change was related to fatigue softening and hardening, and synchronous with the change in the surfac e residual stress.
