Abstract
The effects of elevated temperature and high strain rate on fatigue life and tensile properties were measured for annealed 316 stainless steel and titanium alloy 6Al−2Mo−4Zr−2Sn in the solution-heat-treated and aged condition. A 14-KHz magnetostriction oscillator was used for fatigue testing. This equipment was developed for operation in excess of 2000° F. A split Hopkinson pressure bar provided dynamic tensile data up to 1300° F at strain rates on the order of 103 in./in./sec. An attempt was made to correlate the high-frequency-fatigue data with the dynamic tensile measurements by using the Manson fatiguelife-prediction methods. This paper contains the experimental results and discusses the analysis of these experiments.
