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

Author : Britton T.B., Dunne F.P., Wilkinson A.J.
Description:Proceedings of the Royal Society A, 08 June 2015; volume 471, issue 2178This is an overview of micromechanical deformationmechanisms in hexagonal close-packed metals. Westart with an in-depth discussion of single-crystalbehaviour concerning crystallographic slip, plasticanisotropy and deformation twinning. We move on todiscuss some complexities involved in polycrystallinedeformation and modelling approaches, focusing onrate effects in titanium alloys that are thought to playa significant role in dwell fatigue. We finish our reviewwith a brief commentary on current understandingand state-of-the-art techniques, and outline some keyareas where further study is recommended.
