In this paper we review the work related to amorphization under mechanical stress. Beyond
pressure, we highlight the role of deviatoric or shear stresses. We show that the most recent …

Abstracts Liquid metal embrittlement (LME) is a problematic phenomenon that occurs when
a reactive liquid metal attacks the grain boundaries of ductile solid metal, leading to brittle …

The rheological properties of Earth's lower mantle play a key role for global mantle
dynamics. The mineralogy of the lower mantle can be approximated as a bridgmanite …

Catastrophic brittle failure of ductile materials by liquid metal embrittlement (LME) is a widely
documented phenomenon but the fundamentals of its initiation mechanism are poorly …

Transport of heat from the interior of the Earth drives convection in the mantle, which
involves the deformation of solid rocks over billions of years. The lower mantle of the Earth is …

High-entropy alloys (HEAs) utilizing a deformation-induced martensitic transformation
(DIMT) mechanism have been developed as they exhibit an excellent balance of strength …

Abstract Polycrystalline (Mg, Fe) O ferropericlase is the second most abundant mantle
constituent of the Earth and possibly of super‐Earth exoplanets. Its mechanical behavior is …

Seismic anisotropy is a powerful tool to map deformation processes in the deep Earth.
Below 660 km, however, observations are scarce and conflicting. In addition, the underlying …

To study the viscosity of bridgmanite and ferropericlase aggregate, uniaxial compression
deformation experiments on pre‐synthesized post‐spinel phase and bridgmanite two …

The properties of [001] symmetric tilt grain boundaries (STGBs) in magnesium oxide are
investigated systematically with atomic-scale simulations. Their formation energies, atomic …
