Grain boundary strengthening — (or Hall Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. It is based on the observation that grain boundaries impede dislocation movement and that the number of dislocations within a … Wikipedia
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
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
Dynamic quartz recrystallization — Quartzite from Southern Appalachians. Thin section prepared by Michael Stevens. Quartz is the most abundant single mineral in the earth s crust (behind the feldspar group),[1] and as such is present in a very large proportion of rocks both as… … Wikipedia
Recovery (metallurgy) — Recovery is a process by which deformed grains can reduce their stored energy by the removal or rearrangement of defects in their crystal structure. These defects, primarily dislocations, are introduced by plastic deformation of the material and… … Wikipedia
Recrystallization (metallurgy) — Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains that nucleate and grow until the original grains have been entirely consumed. Recrystallization is usually accompanied by a reduction in the… … 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
Continuous sub-grain rotation type dynamic recrystallization — In Metallurgy, Materials Science and Structural geology continuous sub grain rotation type dynamic recrystallization is recognized as an important mechanism for dynamic recrystallisation. It involves the rotation of initially low angle sub grain… … Wikipedia
