Question

why the grain boundary defects are produced in the materials? Explain the grain boundary in brief
​

Answer 1

Answer:

Grain boundaries are defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material. ... Grain boundaries are usually the result of uneven growth when the solid is crystallizing.

Answer 2

Grain boundary defects are produced in the materials

Explanation:

Grain boundaries are defects in the crystal structure and try to decrease the electrical and thermal conductivity of the material. In other words, it stops dislocations.

The meaning of Grain boundaries is that it is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are 2D defects in the crystal structure and tend to decrease the electrical and thermal conductivity of the material.
