WebFeb 1, 2016 · One classic example is control of the ordered crystal structures of the quasiternary system of Ni 3 V–Co 3 V–Fe 3 V through adjusting the electron concentrations. It is known that the ordered structures of A 3 B intermetallics are built from the regular stacking of the close packed ordered layers, either being of triangular (T) type or … 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].

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific …
WebJan 17, 2024 · The structural order of atoms and molecules increases from liquids to gels, liquid crystals, and, finally, crystals, and the degree of order can be roughly related to the activation energy of structural transformation.
