Abstract | Early failure during dwell-fatigue of titanium alloys is a research of interest as it directly drives the in-service life of critical parts in turbines. A study was undertaken to examine the evolution of life and strain in six specimens made of near-alpha titanium alloy (IMI 834) during dwell-fatigue loading conditions. The strain accumulation in dwell-fatigue test for one sample was significantly different. This specimen presents a different ultrasonic response from that of the other specimens, that is ultrasonic measurements reveal a different macro-texture for this sample. When this specimen is excluded, it is found that ultrasonic speed correlates well with dwell-fatigue life for the remaining samples. This paper evaluates the usefulness of ultrasound waves to predict the strain and the dwellfatigue life of a titanium alloy. |
