Dislocation cores, the regions in the immediate vicinity of dislocation lines, control a number
of properties such as dislocation mobility, cross-slip and short-range interactions with other …

This is an overview of micromechanical deformation mechanisms in hexagonal close-
packed metals. We start with an in-depth discussion of single-crystal behaviour concerning …

The basic framework and-conceptual understanding of the metallurgy of Ti alloys is strong
and this has enabled the use of titanium and its alloys in safety-critical structures such as …

Structural alloys are often strengthened through the addition of solute atoms. However,
given that solute atoms interact weakly with the elastic fields of screw dislocations, it has …

Large scale atomistic simulations provide direct access to important materials phenomena
not easily accessible to experiments or quantum mechanics-based calculation approaches …

In the past twenty years, new experimental approaches, improved models and progress in
simulation techniques have brought new insights into longstanding issues concerning …

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 …

The ease of a metal to deform plastically in selected crystallographic planes depends on the
core structure of its dislocations. As the latter is controlled by electronic interactions, metals …

Twinning-induced plasticity plays a critical role in determining the deformation behaviors of
hexagonal close-packed metals (eg, Mg and Ti), due to the lack of five independent slip …

Ti exhibits complex plastic deformation controlled by active dislocation and twinning
systems. Understandings on dislocation cores and twin interfaces are currently not complete …
