Research on Residual Life Estimation Method for KMN Steel Based on Nonlinear Ultrasonic Testing
The testing of KMN steel bending fatigue with different cycles was carried out using a nonlinear ultrasonic detector to obtain its nonlinear coefficient. The experimental results show that the nonlinear coefficient first increases and then decreases with an increase in fatigue cycles. The relationsh...
