Abstract

ECT technique was applied to evaluate the fatigue damage progression of Cu-Cr-Zr alloy during low-cycle fatigue testing at room temperature. Subtracted ECT-Y signal from the applied strain signal was indicated low-cycle fatigue damage such as work-hardening, micro-crack generation and macro-crack propagation. The damage propagation of the low-cycle fatigue testing in Cu-alloy could be depended on work-hardening inside of the specimen and micro-crack nucleation on the surface.
