An open question in the behavior of metals subjected to shock is the nature of the deformation that couples to the phase transformation process. Experiments to date cannot …

The plasticity and α→ ω transformation are important for the toughness and ductility of hcp titanium under shock loading. However, three questions remain outstanding:(i) what …

The role of grain boundary structures on the shock response of hexagonal-close-packed (hcp) metals is little understood. We use molecular dynamics simulations to investigate …
Under pressure, titanium transforms from the hexagonal-closed-packed (hcp) structure to the high pressure omega phase. This phase transition from hcp (α) to omega (ω) is martensitic …

Manganin stress gauges in lateral orientation have been used to monitor the shock response of Ti–6Al–4V when loaded either parallel to or radial to the long axis of the original …
We present a series of experiments probing the martensitic α–ω (hexagonal close-packed to simple hexagonal) transition in titanium under shock-loading to peak stresses around 15 …

ω-titanium (Ti) is a high-pressure phase that is conventionally perceived to be brittle and nondeformable, although direct investigations of its deformation process remain scarce. In …

Titanium (Ti) with ω phase is always considered brittle and non-deformable. Therefore, little is known of the role of ω phase in the anomalously high plasticity of titanium alloys …
In this study the influence of alloy chemistry on the propensity of omega phase formation in two titanium alloys during shock loading is examined. The effect of peak shock stress on the …
