Grain growth phenomenon during pressure-induced phase transformations at room temperature
Valery I. Levitas, Raghunandan Pratoori, Dmitry Popov +2
Significant grain growth is observed during the high-pressure phase transformations (PTs) at room temperature within an hour for various materials. However, no existing theory expl…
Effect of particle size on the phase transformation behavior and equation of state of Si under hydrostatic loading
Sorb Yesudhas, Valery I. Levitas, Feng Lin +2
High-pressure synchrotron X-ray diffraction (XRD) studies have been conducted on three types of Si particles (micron, 100 nm, and 30 nm). The pressure for initiation of Si-I->Si-II…
Plastic strain-induced olivine-ringwoodite phase transformation at room temperature: main rules and the mechanism of the deep-focus earthquake
Feng Lin, Valery Levitas, Sorb Yesudhas +1
Deep-focus earthquakes that occur at 350-660 km are theorized to be caused by strain-induced olivine-spinel phase transformation (PT). We introduce and apply dynamic rotational dia…
Rules of plastic strain-induced phase transformations and nanostructure evolution under high-pressure and severe plastic flow
Feng Lin, Valery Levitas, Krishan Pandey +2
Rough diamond anvils (rough-DA) are introduced to intensify all occurring processes during an in-situ study of heterogeneous compression of strongly pre-deformed Zr in diamond anvi…
Plastic strain-induced phase transformations in silicon: drastic reduction of transformation pressures, change in transformation sequence, and particle size effect
Sorb Yesudhas, Valery I. Levitas, Feng Lin +2
Pressure-induced phase transformations (PTs) between numerous phases of Si, the most important electronic material, have been studied for decades. This is not the case for plastic…
Simulations of multivariant Si I to Si II phase transformation in polycrystalline silicon with finite-strain scale-free phase-field approach
Hamed Babaei, Raghunandan Pratoori, Valery I. Levitas
Scale-free phase-field approach (PFA) at large strains and corresponding finite element method (FEM) simulations for multivariant martensitic phase transformation (PT) from cubic S…
