The influence of the grain orientation on short crack growth was studied in fatigued austenitic stainless steel (316L). Global and mesotexture were analysed using the electron backscattering diffraction (EBSD) technique in the scanning electron micro

The slip activity of persistent slip bands (PSBs) in polycrystalline nickel was studied using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The half-cycle slip activity as well as the local shear strain amplitudes was investig

The development of slip steps and extrusions on well-polished specimen surfaces was investigated for nickel polycrystals. The specimen was cyclically pre-deformed up to 60% of its lifetime. Further deformation was carried out in situ in a scanning el

The appearance of glide localizations after cyclic deformation in the saturation stage was investigated for polycrystalline nickel. It was shown that persistent slip bands (PSBs) are formed in a wide range of grain orientations. Concerning the grain

We study the influence of texture on the propagation of short cracks on the basis of the evolution of a family of microcracks in 316L austenitic stainless steel under the conditions of symmetric tension-compression. It is shown that the process of cr

The influence of different overstraining events on the crack-opening displacement of microstructurally short cracks in polycrystalline nickel was investigated. Both symmetric and asymmetric overstraining experiments were carried out and the influence

Coherent twin boundaries (TBs) in f.c.c. metals are considered to have low energy. Nevertheless, even TBs are preferred sites for crack nucleation in materials loaded at very small alternating plastic strain amplitudes (high cycle fatigue). In the pr

Crack opening displacement (COD) along the edges of microstructurally short fatigue cracks in austenitic stainless steel was investigated in situ in the SEM. The measured plastic part of the COD range between maximum and minimum load was extrapolated

It is well-known that crack initiation in fatigued austenitic steel (316L) specimens is dominated at lower deformation amplitudes by twin boundaries (TBs). For medium plastic strain amplitudes, it is shown here that the propagation of short cracks st
