Nucleation of dislocations in a homogeneous crystal lattice is relevant for small-scale
plasticity or ultra-fast loading. Previously, we improved the dislocation nucleation theory and …

We present a theoretical framework to accurately predict the lattice mismatch between the
fcc matrix and precipitates in the multi-component aluminum alloys as a function of …

Abstract Knowledge on structures and energetics of vacancy clusters is fundamental to
understand defect evolution in metals. Yet there remain no reliable methods able to …

The determination of ductile-to-brittle transition temperatures (DBTT) in intermetallic
compounds is crucial for assessing their practical applications. In this study, we investigate …

The famous sequence of precipitates which form upon heat treating Al-Cu is part of nearly
every metallurgical textbook. Numerous precipitation (and other) experiments have led to a …

A model is presented to predict the effectiveness of dilute solutes in delaying precipitate
formation, with application to natural and artificial aging in metal alloys. Control of aging is …

A quantum-continuum multiscale coupling of Kohn–Sham density functional theory to
continuum material is presented that can handle mechanics problems in metals when long …

Random solid solution alloys are a broad class of materials that are used across the entire
spectrum of engineering metals, whether as stand-alone materials (eg Al-5xxx alloys) or as …

63Cu NMR has been used to observe the evolution of the precipitate structures in the
solution treated and quenched dilute alloy Al-1.7 at% Cu following thermal aging. The …

In this study, we formulate a mechanical model of spall fracture of copper, which describes
both solid and molten states. The model is verified, and its parameters are found based on …
