High pressure/temperature structural phase transition in vanadium: Influence of non-hydrostatic conditions
(English)Manuscript (Other academic)
Vanadium undergoes a phase transition upon compression from bcc to rhombohedral structure at 62 GPa. In this paper we confirm the bcc to rhombohedral phase transition at 61.5 GPa under quasi hydrostatic compression in Ne pressure medium. Under non-hydrostatic condition we find the phase transition occurring at 30 GPa at ambient temperature, and 37 GPa at 425 K. We find the hydrostatic transition is hindered and it can occur at much lower pressure under non-hydrostatic condition.
