S-N graphs up to 10E10 cycles are presented for different hardmetal grades. Ultrasonic resonance testing is shown to be well suited for fatigue testing of hardmetals. No fatigue “limit” was found but the S-N curves drop consistently. Crack initiation is microstructure-controlled and not defect-controlled.
