It explains how cold working increases dislocation density and how that affects the stress-strain characteristics of steel, particularly the onset of deformation. It describes the effects of deformation on ferrite, austenite, cementite, and pearlite, and how to optimize...

... Abstract Glasses and ceramics are susceptible to stress-corrosion cracking (SCC), as are metals, but the underlying mechanisms differ in many ways. One of the major differences stems from the lack of active dislocation motion that, in metals, serves to arrest cracks by reducing stress...

.... Vacancy diffusion is the movement of a vacancy through the lattice, thereby assisting the diffusion of atoms. The number of dislocations is reduced when the vacancies diffuse to grain boundaries or surfaces, which act as sinks. If a metal is heated to a high temperature, the number of vacancies increases...

... and Structures.” Therefore, at room temperature, microstructures of equiaxed grains of ferrite have high ductility: dislocations can readily move and multiply to produce large permanent changes in the shape of steel structures. However, below room temperature, dislocation movement is restricted and ferritic...
