grain boundary migration मीनिंग इन हिंदी

उदाहरण वाक्य

1. Grain boundary migration plays an important role in many of the mechanisms of creep.
2. During grain boundary migration, the rate determining step depends on the angle between two adjacent grains.
3. Grain boundary migration occurs when a shear stress acts on the grain boundary plane and causes the grains to slide.
4. Since it is beneficial for particles to reside in the grain boundaries and they exert a force in opposite direction compared to the grain boundary migration.
5. At low temperatures, the mobility of the grain boundary may be local, and the grain boundary may bulge into a neighboring grain with a high dislocation density and form new, smaller, independent crystals by a process called low-temperature grain boundary migration, or bulging recrystallization.
6. The structure is thought to result from the interplay of passive flattening and rotation of grains in a non-coaxial flow field on one hand and recrystallisation opposes this by forming new equidimensional grains free of strain ( by grain boundary migration ); in order to achieve strain-free grains, a part of the developing shape fabric simultaneously must be destroyed.
