The grain structure refers to the arrangement of the grains in a metal, with a grain having a particular crystal structure. The grain boundary refers to the outside area of a grain that separates it from the other grains.
How is grain structure formed?
When a metal solidifies from the molten state, millions of tiny crystals start to grow. The longer the metal takes to cool the larger the crystals grow. These crystals form the grains in the solid metal. Each grain is a distinct crystal with its own orientation.
What is grain in crystal structure?
A grain is a bunch of crystals (rather than a unit lattice) arranged in a same direction. When small crystalls growth they can form a polycrystaline structure in wich the small crystals are calling grains.
What is grain in material?
grain, in metallurgy, any of the crystallites (small crystals or grains) of varying, randomly distributed, small sizes that compose a solid metal. Randomly oriented, the grains contact each other at surfaces called grain boundaries.
What type of structure is formed at the grain boundary?
Grain boundaries are defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material. A grain boundary is a general planar defect that separates regions of different crystalline orientation (such as grains) within a polycrystalline solid.
What is grain and grain boundary?
These individual crystals are called"grains." In any one grain, all atoms are arranged with one particular orientation and one particular pattern. The juncture between adjacent grains is called a "grain boundary." The grain boundary is a transition region in which some atoms are not exactly aligned with either grain.
