Pressure-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 ...

temperature 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...

Microstructural 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...

Deformation-induced phase transformation in zinc sulphide

There are two crystalline modifications of zinc sulphide. The high-temperature hexagonal (e) phase and the low-temperature cubic (/~) phase exhibit a reconstructive transformation at a transition temperature of about 1020 ° C. The transformation of e phase back to ~ phase is a sluggish process compared to that of/3 to :~ [1], therefore once it is formed the a phase will remain as a metastable p...

Shock-induced phase transformation in tantalum.

A TEM study of pure tantalum and tantalum-tungsten alloys explosively shocked at a peak pressure of 30 GPa is presented. While no omega phase was found in shock-recovered pure Ta and Ta-5W which mainly contain a cellular dislocation structure, a shock-induced omega phase was found in Ta-10W which contains evenly distributed dislocations with a density higher than 1 × 10(12) cm( - 2). The shock-...
