Grain boundary — A grain boundary is the interface between two grains in a polycrystalline material. Grain boundaries disrupt the motion of dislocations through a material, so reducing crystallite size is a common way to improve strength, as described by the Hall … Wikipedia
Grain growth — refers to the increase in size of grains (crystallites) in a material at high temperature. This occurs when recovery and recrystallisation are complete and further reduction in the internal energy can only be achieved by reducing the total area… … Wikipedia
Creep (deformation) — For other uses, see Creep (disambiguation). v · d · e Materials failure modes Buckling … Wikipedia
Diffusion creep — refers to the deformation of crystalline solids by the diffusion of vacancies through their crystal lattice.[1] Diffusion creep results in plastic deformation rather than brittle failure of the material. Diffusion creep is more sensitive to… … Wikipedia
Coble creep — A diagram showing how atoms and vacancies move through a grain as the mechanism of Coble creep Coble creep, a form of diffusion creep, is a mechanism for deformation of crystalline solids. Coble creep occurs through the diffusion of atoms in a… … Wikipedia
Dislocation creep — is a deformation mechanism in crystalline materials. Dislocation creep involves the movement of dislocations through the crystal lattice of the material. It causes plastic deformation of the individual crystals and in the end the material itself … Wikipedia
Deformation mechanism — In structural geology, metallurgy and materials science, deformation mechanisms refer to the various mechanisms at the grain scale that are responsible for accommodating large plastic strains in rocks, metals and other materials. Contents 1… … Wikipedia
Mylonite — An amphibolitic mylonite showing a number of (rotated) porphyroclasts: a clear red garnet left in the picture while smaller white feldspar porphyroclasts can be found all over. Location: the tectonic contact between th … Wikipedia
Crystallite — Galvanized surface with visible crystallites of zinc. Crystallites in the steel under the coating are microscopic. Crystallites are small, often microscopic crystals that, held together through highly defective boundaries, constitute a… … Wikipedia
Superalloy — A superalloy, or high performance alloy, is an alloy that exhibits excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. Superalloys typically have an austenitic… … Wikipedia
