Ultrasonic fatigue tests at high temperature on an austenitic steel

摘要：

The objective of this paper is to study the gigacycle fatigue behavior of an austenitic steel at temperatures of 600 ℃ and 700 ℃ under fully reverse loading (R = -1). Numerical simulation by finite element method (FEM) was used to design the specimens and to analyze the effects of the variation in the dynamic Young modulus with temperature from measurements of the ultrasonic resonance frequency. Finally, new stress-life curves for this material are presented for a lifetime range from 105to 109 cycles at room temperature, 600℃ and 700℃.
