Sažetak
The effect of different initial microstructures defined by various precipitates morphology was investigated at the creep/fatigue conditions by 900C and 500MPa. The wave form of stress as a function of time for cyclic loading was of trapezoidal shape with a hold time 10 seconds at the upper stress level. TEM was employed to examine the deformation process in a strengthened matrix in dependance of precipitate morphology. the fracture lifetime and cycles up to fracture were the criteria for the evaluate the additional cyclic component effect on of the cource of deformation.
