Term: Guinier-Preston (G-P) Zone

Description: A small precipitation domain in a supersaturated metallic solid solution. A G-P zone has no welldefined crystalline structure of its own and contains an abnormally high concentration of solute atoms. The formation of G-P zones constitutes the first stage of precipitation and is usually accompanied by a change in properties of the solid solution in which they occur.
