An alloy is a mixture of materials which have metallic properties, composed of 2 or more components (elements) and at least a main component is metal.
In general, inter-metal solubility is limited due to the limited replacement of atoms by other atoms or limitations of other atoms between the atoms in the crystal lattice arrangement known in the metal, namely:
Simple cubic not mean so simple but can mean that this structure has only one full unit cell as a unit again, it could be this cubic structure is the most complicated structure among the existing structure, among other example is the Carbon and Manganese.
Face Centerred Cubic namely cubic structure similar to the BCC it appears in the presence of an atom at each corner of the unit cell and there is one atom longer at the center of each side of the cube, among others, for example, austenite Iron, Copper, Nickel, Platinum, Iridium, and Rudium.
Based Center Cubic means every atom in the metal structure is surrounded by eight nearest atoms either atom is located at the corner or in the center of the unit cell so that each atom has approximately the same environment, among others, for example iron Ferrite, Molebdium, chromium, vanadium, thallium.
Hexagonal arrangement of the meeting is the arrangement of the structure which has very regular basis because of certain atoms have the same angle and length, among others, for example zinc, Zirconium, Magnesium, Rhenium.
The composition of these crystals to determine the physical and mechanical properties of metals. Changes in the composition of the crystal lattice due to mixing of metal atoms resulting in changes in crystal plane spacing and number of neighboring atoms that determine the bond atoms will carry the binding effect on physical properties and mechanical.
Crystallization is a process of crystal formation that occurs during freezing, the phase change from liquid to solid phase. Viewed from the crystallization mechanism occurs in 2 stages: - Establishment of core or nucleation - Crystal growth
In the liquid state, the atoms do not have a regular arrangement of certain, in a liquid state, its temperature is relatively high and the atoms have enough energy so it is easy to move, no later arrangement of atoms relative to other atoms.
