Influence of mean stresses and mean strains on the cyclic deformation behavior and the plasticity-induced martensite formation of X6CrNiTi1810 stainless steel

This paper describes some aspects of the fatigue behavior of the metastable austenitic stainless steel X6CrNiTi 1810 (German material number 1.4541). The aim of the present investigation is to determine the influence of plast icity-induced martensite formation on the cyclic deformation behavior at ro om temperature and T = 300 degrees C. Several specimen batches were tested under stress and total strain control with different R-values, a frequency of 5 Hz and triangular load-time functions, sigma-hysteresis and nondestruc tive magnetic measurements are used to characterize the fatigue behavior. C haracteristic results are presented and discussed.
