Abstract:

The effect of torsional pre-strain on the behavior of RC-55 titanium alloy has been studied with rotating beam fatigue tests. Torsional pre-strain ranged from 5 to 60 per cent of the torsional strain to failure. Rotating beam specimens were then machined from the twisted alloy and fatigue-tested at 10,000 rpm and room temperature 70 degrees Fahrenheit. Data from tests of torsionally pre-strained specimens were compared with data from tests of otherwise similar specimens that had not been pre-strained.
