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 interactions between dislocations (dislocations and deformation twins) and boundaries
(grain boundaries, twin boundaries and phase interfaces) during deformation at ambient …

Advanced manufacturing approaches, including additive manufacturing (ie,“3D printing”) of
metallic structures requires a change to qualification strategies. One approach, informed …

The gliding modes of a duplex Ti–6Al–4V titanium alloy were investigated through in situ
(scanning electron microscopy) tensile tests. A method based on electron back-scattering …

The phenomenon of ambient temperature dwell sensitive fatigue in titanium alloys has been
a concern to the gas turbine industries for over three decades. However, largely due to …

Laser-based directed energy deposition (LDED) enables rapid near-net-shape fabrication of
large-scale titanium components for aerospace applications. However, the poor tensile …

Deformation micromechanisms of a Ti–6Al–4V alloy under fatigue loading at room
temperature are studied using a three-dimensional crystal plasticity constitutive model. The …

Lilliputian techniques for measuring the mechanical response of microscale specimens are
being developed to characterize the performance and reliability of microelectromechanical …

A rate dependent crystal plasticity model for the α/β Ti–Al alloy Ti–6Al–4V with duplex
microstructure is developed and presented herein. Duplex Ti–6Al–4V is a dual-phase alloy …

The current understanding of room temperature microplasticity in α/β titanium alloys is
reviewed with a special emphasis on dual-phase engineering alloys. As the interplay …
