Methods that change the properties of metals by heating and cooling, by working them cold, or by pressing and fusing powders. A member belongs here when the cited article describes it as a metal heat treatment, working or powder method. The group is one of the groupings under this field in the Technology Atlas, and each member keeps its own entry with its own cited sources and its own place in the field. Its members appear in the Browse By view for the field, so a reader can move from this group to each member entry and to the sources cited there.

Has Member: Annealing, IntroductionQuote, Has Member: Annealing, Introduction
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.
