Arrangement Of Alloys
Arrangement of alloys is the process of formation of long and close order in the arrangement of atoms of different types on the nodes of the crystal lattice of a solid solution.
An alloy is a substance made by melting two or more elements together, at least one of them metal. An alloy crystallizes upon cooling into a solid solution, mixture, or intermetallic compound. The components of alloys cannot be separated using a physical means. An alloy is homogeneous and retains the properties of a metal, even though it may include metalloids or nonmetals in its composition.
Examples of alloys include stainless steel, brass, bronze, white gold, 14k gold, and sterling silver. Although exceptions exist, most alloys are named for their primary or base metal, with an indication of other elements in order of mass percent.
The arrangement of alloys occurs by diffusion of atoms at a distance of the order of interatomic distances and is accompanied by a change in the physical and mechanical properties of the alloys - the electrical resistance decreases, the modulus of elasticity and hardness increase.
