2. Slip bands in metals - Wikipedia

   en.wikipedia.org/wiki/Slip_bands_in_metals

   PSB structure (adopted from [7]). Persistent slip-bands (PSBs) are associated with strain localisation due to fatigue in metals and cracking on the same plane. Transmission electron microscopy (TEM) and three-dimensional discrete dislocation dynamics (DDD [8]) simulation were used to reveal and understand dislocations type and arrangement/patterns to relate it to the sub-surface structure.

3. Lüders band - Wikipedia

   en.wikipedia.org/wiki/Lüders_band

   After the band has passed through the material the deformation proceeds uniformly with positive strain hardening. Sometimes Lüders band transition into the Portevin–Le Chatelier effect while changing the temperature or strain rate , this implies these are related phenomena [ 4 ] Lüders bands are known as a strain softening instability.

4. Fatigue (material) - Wikipedia

   en.wikipedia.org/wiki/Fatigue_(material)

   Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved.

6. Corrosion fatigue - Wikipedia

   en.wikipedia.org/wiki/Corrosion_fatigue

   Fractures are initiated either by pitting or persistent slip bands. [3] Corrosion fatigue may be reduced by alloy additions, inhibition and cathodic protection, all of which reduce pitting. [ 4 ] Since corrosion-fatigue cracks initiate at a metal's surface, surface treatments like plating, cladding, nitriding and shot peening were found to ...

8. Slip (materials science) - Wikipedia

   en.wikipedia.org/wiki/Slip_(materials_science)

   Typically, slip bands induce surface steps (i.e. roughness due persistent slip bands during fatigue) and a stress concentration which can be a crack nucleation site. Slip bands extend until impinged by a boundary, and the generated stress from dislocation pile-up against that boundary will either stop or transmit the operating slip. [9] [10]
