Fatigue Damage Detection in SLM-Formed Alloy Layers Based on Nonlinear Ultrasonic Technology

Utilizing the ultrasonic nonlinear coefficient, the fatigue damage state of specimens can be accurately determined. This study rapidly assessed the fatigue damage of selective laser melting(SLM) GH4169 nickel-based alloy layers through higher harmonic detection techniques. Results showed that obviou...
