WebDec 15, 2024 · Crystal Structure of Metal and Alloys. Crystals are three-dimensional repeating patterns. The fundamental repeating unit of the crystal is called the unit cell. It is a three-dimensional shape that may be replicated indefinitely using unit translations to fill holes in the structure. Usually, a crystal has one of three major structures: WebCrystal Structure of Metals: When a metal is melted, metallic atoms detach themselves from other metallic atoms and vibrate rapidly in random directions. For solidification of metal from liquid stage, all that is required it that a sufficient number of atoms may exist in the proper arrangement so that a crystal may grow.
