Hexagonal close-packed (hcp) metals such as Mg, Ti, and Zr are lightweight and/or durable
metals with critical structural applications in the automotive (Mg), aerospace (Ti), and …

Dislocation core structures of hcp metals are highly complex and differ significantly among
the hcp family. Some dislocations undergo unconventional transformations that have …

We present a new approach for calculating generalized stacking-fault energies, which
allows for in-plane relaxation of atoms. When applied to the {11 2} slip plane in hcp …

In hexagonal-closed-pack (HCP) metals, slip of< c+a> disloc ations on pyramidal planes is
considered to be the most difficult slip mode that controls the overall plastic behavior …

A review is presented on the role of dislocation cores and planar faults in activating the
nonbasal deformation modes,< c+ a> pyramidal slip and deformation twinning, in hcp metals …

Alloying magnesium (Mg) with rare earth elements such as yttrium (Y) has been reported to
activate the pyramidal< c+ a> slip systems and improve the plasticity of Mg at room …

The plastic deformation in hcp metals is complex, with the associated dislocation core
structures and properties not well understood on many slip planes in most hcp metals. A first …

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 …

A possible source mechanism for non-basal〈 c+ a〉 slip dislocations is proposed based on
the formation of an attractive junction between glissile〈 a〉 and sessile c dislocations from …

Temperature effects on the mobility of< c+ a> dislocations on pyramidal planes are
characterized by molecular dynamics simulations. On the first-order pyramidal planes, near …
