Metallic Structure

Metallic structure refers to the arrangement of metal atoms in a solid. The arrangement of metal atoms can be granular, crystalline, or amorphous.

Granular Structure

A granular structure refers to a metal structure that is composed of granules or grains. The grains are usually visible to the naked eye and are formed when molten metal solidifies.

Wrought Structure

Wrought structure refers to the arrangement of metal atoms in a metal that has been worked or shaped by mechanical or thermal means. This type of structure is often found in metals that have been forged, rolled, or drawn.

Amorphous Structure

An amorphous structure refers to a metal structure that lacks long-range order or crystalline structure. This type of structure is usually found in metals that have been rapidly cooled, such as in the case of metallic glasses.

Crystalline Structure

A crystalline structure refers to a metal structure that has a repeating pattern of atoms in three dimensions. This type of structure is often found in metals that have been slowly cooled, allowing the atoms to arrange themselves in an ordered pattern.

Conclusion

In structure, all metals are crystalline, meaning they have a repeating pattern of atoms in three dimensions. This is due to the way in which metals solidify, allowing the atoms to arrange themselves in an ordered pattern as the metal cools.
