Abstract Current state and historical progress in experimental theoretical studies of surface relief appertaining to persistent slip bands (PSBs) leading fatigue crack initiation cyclically deformed metals is presented as a thorough critical overview. A comprehensive inventory microscopic techniques used for this study tabulated chronologically with emphasis their applicability polycrystals. The most relevant characteristics concerning evolution, namely the form extrusions intrusions single-...
Early stages of surface relief evolution persistent slip markings (PSMs), formed in areas where bands (PSBs) intersect the free surface, polycrystalline 316L stainless steel cycled with constant plastic strain amplitude were studied using atomic force microscopy (AFM) and electron backscattering diffraction (EBSD). Focused ion beam (FIB) technique was employed to obtain additional, more detailed information on shape PSMs. To reveal true qualitative quantitative simultaneous growth intrusions...
Abstract— The cyclic stress‐strain response of two heats austenitic stainless steel 3 16L was experimentally studied under a wide range plastic strain amplitudes. Three domains on the stress‐ curve were found. In middle domain plateau behaviour corresponds to fatigue softening. at low amplitudes is characterized by stabilized and highest continuous hardening. Individual correlated with observed dislocation structures. existence can be related localization into persistent slip bands. A...
Solution-annealed AISI 316L steel was fatigued with constant plastic strain amplitudes at room temperature and under various conditions depressed temperatures down to 113 K reveal its stability against deformation-induced martensite formation. Microstructural changes induced by fatigue were characterized transmission electron microscopy (TEM), channeling contrast imaging (ECCI) backscattering diffraction (EBSD) techniques. Neutron magnetic induction method adopted for quantification of...
The early stages of fatigue damage in cyclic loading several polycrystalline materials were studied. initiation cracks is influenced by a number factors like the presence inclusions, grain size and creep strain. growth short was measured symmetrical cycling with positive mean stress. kinetics crack affected secondary can be approximated an exponential law. integrated law equivalent to Coffin-Manson allowing interpretation this terms growth.
