In materials science, slip is the large displacement of one part of a crystal relative to another part along crystallographic planes and directions. [1] Slip occurs by the passage of dislocations on close/packed planes, which are planes containing the greatest number of atoms per area and in close-packed directions (most atoms per length).
Pottery on which slip has been applied either for glazing or decoration is called slipware. Engobe, from the French word for slip, is a related term for a liquid suspension of clays and flux, in addition to fillers and other materials. This is in contrast to slips, which are historically considered to be a liquid suspension of only clay or ...
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.
Away from the melting point of a material, vacancy diffusion is a slow process, so jogs act as immobile barriers at room temperature for most metals. [21] Jogs typically form when two non-parallel dislocations cross during slip. The presence of jogs in a material increases its yield strength by preventing easy
Slip (vehicle dynamics), the relative motion between a tire and the road surface; Slip (electrical motor), the difference in speed between the frequency supplied to an induction motor and rotor shaft speed; Slip, a type of rail switch; Slip gauge or gauge block, a system for producing precision lengths
Schmid's Law states that the critically resolved shear stress (τ) is equal to the stress applied to the material (σ) multiplied by the cosine of the angle with the vector normal to the glide plane (φ) and the cosine of the angle with the glide direction (λ). Which can be expressed as: [2] =

the solids content of the slip, the clay:non-plastic ratio in the slip, the chemicals in the slip, either deliberately added or introduced from the raw materials and water, the type and amount of deflocculant, the ambient conditions, especially temperature and humidity, and; the amount of energy involved in mixing the raw materials to prepare ...
