Collective nature of plasticity in mediating phase transformation under shock compression

H Zong, X Ding, T Lookman, J Li, J Sun, EK Cerreta… - Physical Review B, 2014 - APS
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 …

Orientation and grain-boundary dependence of shock-induced plasticity and transformation in nanocrystalline Ti

L Wang, B Li, XL Deng, WR Jian, M Shang, L Deng… - Physical Review B, 2019 - APS
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 …

Twin boundary activated α→ ω phase transformation in titanium under shock compression

H Zong, X Ding, T Lookman, J Sun - Acta Materialia, 2016 - Elsevier
The role of grain boundary structures on the shock response of hexagonal-close-packed

[图书][B] A theoretical study of the hcp to omega martensitic phase transition in titanium

DR Trinkle III - 2003 - search.proquest.com
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 …

The role of anisotropy in the response of the titanium alloy Ti–6Al–4V to shock loading

JCF Millett, G Whiteman, NK Bourne… - Journal of Applied …, 2008 - pubs.aip.org
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 …

[HTML][HTML] The α–ω phase transition in shock-loaded titanium

DR Jones, BM Morrow, CP Trujillo, GT Gray… - Journal of Applied …, 2017 - pubs.aip.org
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 …

Transformation-induced plasticity in omega titanium

AH Zahiri, J Ombogo, T Ma, P Chakraborty… - Journal of Applied …, 2021 - pubs.aip.org
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 …

Phase transformation mediated anomalous plasticity of titanium under severe loading conditions

T Li, H Zong - International Journal of Mechanical Sciences, 2023 - Elsevier
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 …

The influence of oxygen content on the α to ω phase transformation and shock hardening of titanium

E Cerreta, GT Gray, AC Lawson, TA Mason… - Journal of applied …, 2006 - pubs.aip.org
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 …
