γ-α isostructural transition in cerium.
We present zero-temperature first-principles calculations of elemental cerium and we compute its pressure-volume phase diagram within a theoretical framework able to describe simultaneously both the α and the γ phases. A surprising result revealed by our study is the presence of a clear signature of the transition at zero temperature and that this signature can be observed if and only if the sp...
متن کاملPressure-induced structural phase transformation in cobalt(II) dicyanamide.
In situ synchrotron powder diffraction has been used to probe the pressure-dependent structural properties of the magnetic molecular framework material Co(dca)2 [dca = dicyanamide or N(CN)2(-)]. An orthorhombic (Pmnn) to monoclinic (P2₁/n) transformation to a high-pressure phase, namely γ-Co(dca)2, occurs at 1.1 GPa. Structural determination of γ-Co(dca)2 shows that the rutile-like topology of ...
متن کاملtemperature dependence of phase transformation pressure in silicon
in this experimental work the pressure induced phase transformation of silicon and germaniumhas been studied. it was shown that at a particular value of applied pressure, (pt), depending on the sampletemperature, the electrical resistance of the specimen falls off to a metallic state. the main goal of this studywas to find out how the phase transformation pressure, pt, for a p-type silicon vari...
متن کاملMicrostructural evolution and phase transformation in twinning-induced plasticity steel induced by high-pressure torsion
The microstructural evolution of twinning-induced plasticity steel during high-pressure torsion (HPT) processing at 573 K was systematically evaluated. Due to the high processing temperature, the formation of a homogeneous nanostructure was primarily dominated by complicated dislocation and grain boundary activities in lieu of deformation twinning. Apart from the grain refinement process, phase...
متن کاملExperimental evidence for a high-pressure isostructural phase transition in osmium.
We have measured the isothermal equation of state (EOS) of osmium to 75 GPa under hydrostatic conditions at room temperature using angle-dispersive x-ray diffraction. A least-squares fit of this data using a third-order Birch-Murnaghan EOS yields an isothermal bulk modulus K0=411+/-6 GPa, showing osmium is more compressible than diamond. Most importantly, we have documented an anomaly in the co...
