twin boundary meaning in Hindi

Examples

1. Like a grain boundary, a twin boundary has different crystal orientations on its two sides.
2. In Bernal stacked graphene, twin boundaries are common; transitioning from AB to BA stacking.
3. Examples include coherent twin boundaries ( ?3 ) and high-mobility boundaries in FCC materials ( ?7 ).
4. This was attributed to the onset of nanoscale twin boundary formation, an additional deformation mechanism that was not in effect at higher temperatures.
5. The application of a magnetic field or of an external stress shifts the boundaries of the variants, called " twin boundaries ", and thus favors one variant or the other.
6. Twin boundaries are partly responsible for shock hardening and for many of the changes that occur in cold work of metals with limited martensitic transformations : the motion of twin boundaries is responsible for the pseudoelastic and shape-memory behavior of nitinol, and their presence is partly responsible for the hardness due to quenching of steel.
