Pressure-Induced Martensitic Phase Transformation and Microstructure Evolution in nanograined Alloy
Mrinmay Sahu, Sorb Yesudhas, Valery I. Levitas +1
The Fe-Mn-based alloys are receiving immense attention due to their applications in the third generation of advanced high-strength steels, owing to their high strength and ductilit…
Coupled plastic strain- and stress-induced phase transformations and microstructure evolution in Fe-7%Mn alloy in a dynamic rotational diamond anvil cell
Sorb Yesudhas, Mrinmay Sahu, Valery I. Levitas +3
Studies of severe plastic deformation (SPD), microstructure evolution, and plastic strain-induced phase transformations (PTs) are crucial for various fundamental and applied discip…
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…
In-situ study of rules of nanostructure evolution, severe plastic deformations, and friction under high pressure
Feng Lin, Valery I. Levitas, Krishan K. Pandey +2
Severe plastic deformations under high pressure are used to produce nanostructured materials but were studied ex-situ. We introduce rough diamond anvils to reach maximum friction e…
Rough diamond anvils: Steady microstructure, yield surface, and transformation kinetics in Zr
Feng Lin, Valery Levitas, Krishan Pandey +2
Study of the plastic flow and strain-induced phase transformations (PTs) under high pressure with diamond anvils is important for material and geophysics. We introduce rough diamon…
Origin of superconductivity and giant phonon softening in TlInTe under pressure
Sorb Yesudhas, N. Yedukondalu, Manoj K. Jana +12
Analogous to 2D layered transition metal dichalcogenides, the TlSe family of 1D chain materials with Zintl-type structure exhibits exotic phenomena under high-pressure. In the pres…
Lattice frustration in spin-orbit Mott insulator Sr3Ir2O7 at high pressure
Jianbo Zhang, Dayu Yan, Sorb Yesudhas +13
The intertwined charge, spin, orbital, and lattice degrees of freedom could endow 5d compounds with exotic properties. Current interest is focused on electromagnetic interactions i…
Prolonged mixed phase induced by high pressure in MnRuP
Raimundas Sereika, Wei Wu, Changyong Park +10
Hexagonally structured MnRuP was studied under high pressure up to 35 GPa from 5 to 300 K using synchrotron X-ray diffraction. We observed that a partial phase transition from hexa…
