WebThere are 7 crystal systems in 3D, which directly connect to 32 point groups when adding mirror planes and inversion. The 7 crystal systems are: Cubic, Hexagonal, Tetragonal, Trigonal, Orthorhombic, Monoclinic, Triclinic. The crystal systems are listed in order of decreasing symmetry. WebThese materials are known to have crystal structure and properties that are different from their parent metals [3]. They have a long-range ordered crystal structure that gives them unique properties, such as increasing yield strength with increasing temperature, usually up to the melting temperature [16].
