The effect of biaxiality in creep-fatigue interaction at elevated temperature is being investigated. Biaxial fatigue tests were conducted with thin-walled tubular specimens loaded with axial tension-compression and torsion. Biaxial strains were imposed under synchronous loading condition at 25 cycles per minute. Specimens were obtained from extruded 304 stainless steel rods, machined to specifications and annealed in an argon atmosphere at 2000 deg F. The experimental data covers uniaxial and biaxial fatigue tests at 1000 deg F and uniaxial and biaxial cumulative fatigue damage tests under a high to low loading sequence at 1000 and 1200 deg F..
