Giant segregation transition as origin of liquid metal embrittlement in the Fe-Zn system
Reza Darvishi Kamachali, Theophilus Wallis, Yuki Ikeda +5
A giant Zn segregation transition is revealed using CALPHAD-integrated density-based modelling of segregation into Fe grain boundaries (GBs). The results show that above a threshol…
Glass fracture surface energy calculated from crystal structure and bond-energy data
Marco Holzer, Tina Waurischk, Janine George +2
We present a novel method to predict the fracture surface energy, γ, of isochemically crystallizing silicate glasses using readily available crystallographic structure data of thei…
Shear-band cavitation determines the shape of the stress-strain curve of metallic glasses
A. Das, C. Ott, D. Pechimuthu +4
Metallic glasses are known to have a remarkably robust yield strength, admitting Weibull moduli as high as for crystalline engineering alloys. However, their post-yielding behavior…
Micro-plasticity in a fragile model binary glass
P. M. Derlet, R. Maass
Atomistic deformation simulations in the nominally elastic regime are performed for a model binary glass with strain rates as low as /sec (corresponding to 0.01 shear strai…
Emergent structural length scales in a model binary glass --- the micro-second molecular dynamics time-scale regime
Peter M Derlet, Robert Maass
It is now possible to routinely perform atomistic simulations at the microsecond timescale. In the present work, we exploit this for a model binary Lennard-Jones glass to study str…
Shapes and velocity relaxation of dislocation avalanches in Au and Nb single crystals
Gregory Sparks, Robert Maass
We capture the spatiotemporal velocity dynamics of dislocation avalanches in face-centered cubic (FCC) gold and body-centered cubic (BCC) niobium crystals by compression testing of…
