Phase transitions are a common phenomenon in condensed matter and act as a critical
degree of freedom that can be employed to tailor the mechanical or electronic properties of …

The effects of uniaxial stress on the pressure-induced α→ ω transition in pure titanium (Ti)
are investigated by means of angle dispersive X-ray diffraction in a diamond-anvil cell …

Impurities control phase stability and phase transformations in natural and man-made
materials, from shape-memory alloys to steel to planetary cores. Experiments and empirical …

Structures Under Crash and Impact: Continuum Mechanics, Discretization and Experimental
Characterization examines the testing and modeling of materials and structures under …

We propose a new direct mechanism for the pressure driven α→ ω martensitic
transformation in pure titanium. A systematic algorithm enumerates all possible pathways …

Understanding the behavior of materials at extreme pressures is a central issue in fields like
aerodynamics, astronomy, and geology, as well as for advancing technological grand …

Abstract Pure Ti (99.4 pct) is processed by high-pressure torsion (HPT) at applied pressures
in a wide range of 1.2 to 40 giga-pascals (GPa) for equivalent strain up to~ 200. X-ray …

Morphological and compositional evolution of omega (ω) precipitates in a model Titanium-
20 wt% Vanadium (or 19 at.% V) alloy has been systematically investigated by coupling …

Transition metals Ti, Zr, and Hf have a hexagonal close-packed structure (α) at ambient
conditions, but undergo phase transformations with increasing temperature and pressure. Of …

We present a study of the stability of n-vacancies (V n) and hydrogens in the hexagonal
close-packed titanium system computed by means of first-principles calculations. In this …
