WebThe main advantages of annealing are in how the process improves the workability of a material, increasing toughness, reducing hardness and increasing the ductility and machinability of a metal. The heating and cooling process also reduces the brittleness of metals while enhancing their magnetic properties and electrical conductivity. Disadvantages WebOct 7, 2024 · Annealing is a form of heat treatment that brings a metal closer to its equilibrium state. It softens metal, making it more workable and providing for greater ductility. In this process, the metal is heated above its upper critical temperature to change its microstructure. Afterward, the metal is slow-cooled.
