During the annealing stage known as recovery
Did you know?
The three stages of the annealing process that proceed as the temperature of the material is increased are: recovery, recrystallization, and grain growth. The first stage is recovery, and it results in softening of the metal through removal of primarily linear defects called dislocations and the internal stresses they cause. See more In metallurgy and materials science, annealing is a heat treatment that alters the physical and sometimes chemical properties of a material to increase its ductility and reduce its hardness, making it more workable. It … See more Annealing occurs by the diffusion of atoms within a solid material, so that the material progresses towards its equilibrium state. Heat increases the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of … See more In the semiconductor industry, silicon wafers are annealed to repair atomic level disorder from steps like ion implantation. In the process step, dopant atoms, usually boron, phosphorus or arsenic, move into substitutional positions in the crystal lattice, which allows … See more Resistive heating can be used to efficiently anneal copper wire; the heating system employs a controlled electrical short circuit. It can be advantageous because it does not require a See more The high temperature of annealing may result in oxidation of the metal's surface, resulting in scale. If scale must be avoided, annealing … See more Typically, large ovens are used for the annealing process. The inside of the oven is large enough to place the workpiece in a position to receive maximum exposure to the circulating heated air. For high volume process annealing, gas fired conveyor furnaces are often … See more Normalization Normalization is an annealing process applied to ferrous alloys to give the material a uniform fine-grained structure and to avoid … See more WebDec 31, 2004 · This chapter is concerned only with recovery, which occurs on annealing after prior deformation.
