Unveiling the Atomistic Mechanisms of Shear-Induced LDAHDA Transformations and Shear Banding in Amorphous Silicon under High Pressures
Hao Chen, Valery I. Levitas, Tengyi Liu +3
Large-scale molecular dynamics simulations of shear deformation under constant pressures of amorphous silicon, PT from low-density-amorphous (LDA) to high-density-amorphous (HDA) S…
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…
Uncovering origins of heterogeneous superconductivity in LaNiO using quantum sensors
Srinivas V. Mandyam, Esther Wang, Zhipan Wang +7
The family of nickelate superconductors have long been explored as analogs of the high temperature cuprates. Nonetheless, the recent discovery that certain stoichiometric nickelate…
Severe plastic deformations, mechanochemistry, and microstructure evolution under high pressure: In Situ Experiments, Four-Scale Theory, New Phenomena, and Rules
Valery I. Levitas
Processes involving severe plastic deformations (SPD) and phase transformations and chemical reactions (PTs/CRs) under high pressures are widespread for obtaining new nanostructure…
Severe Plastic Deformation of Ceramics by High-Pressure Torsion: Review of Principles and Applications
Kaveh Edalati, Jacqueline Hidalgo-Jiménez, Thanh Tam Nguyen +8
Ceramics are typically brittle at ambient conditions due to their covalent or ionic bonding and limited dislocation activities. While plasticity, and occasionally superplasticity,…
