Grain size typically increases with temperature because at higher temperatures, atoms have more energy and can move more freely. This increased mobility allows grains to grow larger as neighboring grains can merge together. Additionally, higher temperatures can promote the recrystallization process, which results in the formation of larger grains.

What will be the grain size on the effect of high temperature?
High temperature can significantly influence grain size in materials, typically leading to grain growth. As temperature increases, atomic mobility rises, allowing grains to expand and coalesce, resulting in larger grain sizes. This can enhance properties such as ductility but may reduce strength. However, the specific effect on grain size also depends on the material and the duration of exposure to high temperatures.
The factor by which grain size increases with each texture category?
Grain size typically increases by a factor of 2-4 for each texture category. For example, from fine to medium grain size, there is a doubling or quadrupling of grain size. This progression helps geologists classify rocks based on their crystal sizes.
Why FWHM increase with increase in grain size in XRD?
The Full Width at Half Maximum (FWHM) in XRD increases with an increase in grain size because larger grains have more crystalline imperfections (e.g., grain boundaries, dislocations) that contribute to broadening of the diffraction peaks. As the grain size increases, these imperfections become more pronounced, leading to broader diffraction peaks and a larger FWHM.
Why permeability increases with increase in grain size?
Permeability increases with grain size because larger grains create larger pore spaces between them, allowing fluids to flow more freely. In addition, the connectivity of these larger pores typically improves, facilitating the movement of fluid through the material. This relationship is especially pronounced in granular materials, where the arrangement and size of grains significantly influence the ease of fluid passage. Consequently, as grain size increases, the overall flow capacity of the material enhances.
How is recrystallization temperature related to the grain size?
The recrystallization temperature is the temperature at which new strain-free grains begin to form in a deformed material. In general, materials with smaller grain sizes have lower recrystallization temperatures because there are more grain boundaries present, which promote the nucleation of new grains during recrystallization. Conversely, materials with larger grain sizes may require higher temperatures for recrystallization to occur due to fewer grain boundaries inhibiting grain growth.

How grain size depends on the temperature of liquid metal?
It doesn't, it depends on how fast the metal was cooled.
What process changes the grain size of a metamorphic rock?
In order to decrease the pressure within our respiratory tract, we have to expand our container. Our container is basically our thorax. If we can expand our thorax, the air pressure within our thoracic cavity will fall, and air will rush into our respiratory tract. The diaphragm is our primary means to increase our thoracic cavity
