Hi
I want to know what is inside a grain boundary?
Is it a gas or vacuum

There could be gases, but it's essentially the same space that is between atoms - or the same space that exists between the nucleus and atomic electrons. At the atomic level, vacuum really doesn't mean anything.pukb said:Hi

Grain boundaries are interfaces between individual grains in a polycrystalline material.
Grain boundaries play a crucial role in determining the mechanical, electrical, and chemical properties of materials. They can also affect the growth and structure of crystals, as well as the diffusion of atoms within a material.
Grain boundaries are formed during the solidification process when individual crystals grow and merge together. They can also form due to deformation or recrystallization processes.
The properties of grain boundaries are influenced by factors such as their orientation, width, and crystallographic misorientation between adjacent grains. They can also be affected by impurities or defects within the boundary itself.
Yes, grain boundaries can be manipulated through processes such as annealing, which can change the properties and structure of the boundary. They can also be controlled through the use of additives or specific processing techniques to minimize their negative effects on material properties.
