Outline of Final Research Achievements

As a fundamental study of fatigue durability investigation and its diagnostic technique under high-strain rate and high-cycle loading, we have performed gigacycle fatigue test using an ultrasonic fatigue testing machine to investigate the nondestructive detection technique of fatigue crack initiation and propagation. Fatigue strength of solution-annealed and cold-worked austenitic stainless steel SU316L up to 10^9 cycles under room temperature and 250 degC were evaluated. Furthermore, the mechanisms of abrupt temperature rise observed in the fatigue test were experimentally and analytically investigated.
