On the mechanistic basis of deformation at the microscale in hexagonal close-packed metals

Proceedings of the Royal Society A, 08 June 2015; volume 471, issue 2178
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 crystallographic slip, plastic
anisotropy and deformation twinning. We move on to
discuss some complexities involved in polycrystalline
deformation and modelling approaches, focusing on
rate effects in titanium alloys that are thought to play
a significant role in dwell fatigue. We finish our review
with a brief commentary on current understanding
and state-of-the-art techniques, and outline some key
areas where further study is recommended.
