Grain structure of metal

WebThe crystal grain size and phase composition depend on the heating and cooling rates and these, in turn, determine the material properties. Hot or cold working of the pieces of metal following annealing alters the material structure once more, so further heat treatments may be required to attain the desired properties. WebJun 30, 2024 · Sometimes, the structure of the grains themselves cause stress to the metal. During the first phase of the annealing process, called recovery, a furnace or other type of heat source is utilized to raise the temperature of the material to a point that removes internal stresses.
