• 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

• Deformation Bands — are small faults with very small displacements. In the past, these bands have been called Luder s bands or braided shear fractures.[1][2] They often proceed large faults. They develop in porous rocks, like sandstone. Material in a deformation… …   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

• 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

• Deformation (engineering) — This article is about deformation in engineering. For a more rigorous treatment, see Deformation (mechanics). Compressive stress results in deformation which shortens the object but also expands it outwards. In materials science, deformation is a …   Wikipedia

• Deformation mechanism map — A deformation mechanism map is a way of representing the dominant deformation mechanism in a material loaded under a given set of conditions and thereby its likely failure mode. Deformation mechanism maps consist of some kind of stress plotted… …   Wikipedia

• Deformation mechanism maps — A deformation mechanism map is a way of determining the expected failure mode of a material loaded under a given set of conditions. Typical deformation mechanism maps consist of some kind of stress plotted against some kind of temperature axis.… …   Wikipedia
