Deformation twinning in hexagonal materials

Due to the scarcity of “easy slip” systems in hexagonal materials with a hexagonal closepacked structure (hcp), deformation twinning plays a crucial role in determining mechanical properties and texture evolution. In this article, we highlight the current understanding of mechanisms and mechanics of the twinning system {1012}〈1011〉, which is commonly activated in all hexagonal materials for nucleation and propagation of deformation twins, …
