Fatigue testing and properties of hardmetals in the gigacycle range [PDF]
International Journal of Refractory Metals and Hard Materials, 2017 Hardmetal products are frequently fatigue loaded in service, such as e.g. cutting tools for milling or percussion drills. In the present work, the fatigue behaviour of hardmetals was investigated into the gigacycle range using ultrasonic resonance fatigue testing at 20 kHz in push-pull mode at R = - 1.

Gigacycle fatigue in high-strength steels
DENKI-SEIKO[ELECTRIC FURNACE STEEL], 2004 This report introduces our recent research on gigacycle fatigue in high-strength steels using an ultrasonic fatigue testing machine. In evaluating gigacycle fatigue properties of the high-strength steels, fatigue tests and inclusion inspections are essential.
