2Grain 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 …
3Grain 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… …
4Grain boundary depletion — is a mechanism of corrosion, when grain boundaries are depleted of some elements, changing their properties.Intergranular corrosion and selective leaching often involve grain boundary depletion mechanisms …
5Grain 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 …
6grain — grainer, n. grainless, adj. /grayn/, n. 1. a small, hard seed, esp. the seed of a food plant such as wheat, corn, rye, oats, rice, or millet. 2. the gathered seed of food plants, esp. of cereal plants. 3. such plants collectively. 4. any small,… …
7Continuous 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… …

9Crystallite — 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… …
10Crystal structure — In mineralogy and crystallography, crystal structure is a unique arrangement of atoms or molecules in a crystalline liquid or solid. A crystal structure is composed of a pattern, a set of atoms arranged in a particular way, and a lattice… …
