61Geometric dynamic recrystallization — (GDR) is a recrystallization mechanism that has been proposed to occur in several alloys, particularly aluminium, at high temperatures and low strain rates. It is a variant of dynamic recrystallization. The basic mechanism is that during… …
62Zener pinning — is the influence of a dispersion of fine particles on the movement of low and high angle grain boundaries through a polycrystalline material. Small particles act to prevent the motion of such boundaries by exerting a pinning pressure which… …
63steel — steellike, adj. /steel/, n. 1. any of various modified forms of iron, artificially produced, having a carbon content less than that of pig iron and more than that of wrought iron, and having qualities of hardness, elasticity, and strength varying …

66Red-short — is the quality possessed by carbon steel that suffers from having too much sulfur as an impurity.Iron or steel, when heated to above 900 °F (480 °C), glows with a red color, the color being indicative of the temperature in circumstances of low… …
67Intergranular corrosion — (IGC), also termed intergranular attack (IGA), is a form of corrosion where the boundaries of crystallites of the material are more susceptible to corrosion than their insides. ( Cf. transgranular corrosion.)This situation can happen in otherwise …
68Liquid metal embrittlement — is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when tested in the presence of specific liquid metals. Generally, a tensile stress, either externally… …
69Coble 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… …
70Deformation 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… …
