Resumen:
The objective of this paper is to study the gigacycle fatigue behavior of an austenitic steel at temperatures of 600 ºC and 700 ºC 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 1E5 to 1E9 cycles at room temperature, 600 ºC and 700 ºC.
