Ultrasonic Fatigue of Commercial Alloys [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1978
A machine capable of fatigue testing high-strength alloys at 20 kHz and for temperatures up to 900 °C is described. An electrostatic approach used to measure specimen vibration amplitudes at temperature is also discussed, as well as methods to calculate the applied stress. The machine has been used to study the processes of fatigue crack initiation and
