Study Notes
Crystalline Structures
- Crystalline structures have a three-dimensional array.
- The properties of solid metals are determined by the arrangement of atoms in the crystal lattice.
- The regularity of the structure in crystalline materials is described by the term "crystallinity".
- The regular pattern of crystalline structure breaks down at the glass transition stage during the solidification of molten metal.
- Materials with constituent atoms or ions arranged in a regular, repetitive, and symmetrical array are crystalline materials.
