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.
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 ...
Lüders bands are a type of plastic bands, slip band or stretcher-strain mark which are formed due to localized bands of plastic deformation in metals experiencing tensile stresses, common to low-carbon steels and certain Al-Mg alloys. [1]
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]

Slip bands formation near a grain boundary. The dashed lines stand for slip planes. Macroscopic plasticity are well-described by continuum model. Dislocations motions are characterized by an average velocity = ¯ which is known as Orowan's equation.
These coherent α 2 particles lead to easy crack nucleation and fast crack propagation within the planar slip bands. [5] Therefore, toughness of titanium alloy is decreased. Multiple vacuum arc melting (VAR) technique can be used to minimize the oxygen content and increase the toughness of the alloy.
