= Guinier–Preston zone
{wiki=Guinier–Preston_zone}
The Guinier–Preston zone, often referred to simply as the Guinier–Preston (GP) zone, is a concept in materials science and crystallography that describes a specific type of atomic ordering in certain alloys, particularly in aluminum alloys and some other metal systems. It refers to a coherent zone or region that forms in the metal matrix during the aging process, where solute atoms, such as magnesium or copper, segregate to form clusters or precipitates.
