The following points are dealt with: (i) Extent and distribution of cyclic plastic deformation. (ii) Sensitivity of the fatigue behaviour in the HCF and UHCF regions to the start-up procedure of the test and to the preceding stress-strain history. (iii) Role of persistent slip bands (PSBs) and the microcrack initiation in the HCF and UHCF regions. (iv) Dependence of the notch sensitivity on the amplitude of cycling. (v) Effect of high number of very small amplitude cycles on creep behaviour of superalloy single crystals.
