Despite numerous studies of the deformation behavior of magnesium (Mg), its microstructural evolution at different temperatures and strain rates remains largely …
The generation and structures of first-and second-order pyramidal< c+ a> dislocations, 1/3 {1 0 1¯ 1}< 1¯ 1¯ 2 3> and 1/3 {1 1 2¯ 2}< 1¯ 1¯ 2 3>, are determined in pure magnesium …
Slip of pyramidal< c+ a> dislocations in hexagonal close-packed (hcp) crystals is a requisite for accommodation of homogeneous c-axis deformation. However, fundamental aspects of …
