Composition effect in the thermo-mechanical behavior of glasses, and its modelization
Rene Alvarez-Donado, Matias Sepulveda-Macias, Anne Tanguy
We employed molecular dynamics simulations to explore comparatively the thermo-mechanical behavior of two glass materials-an oxide silica glass (SiO2) and a binary Cu-Zr-based meta…
Transmutation-accelerated sampling method for multi-component ZrCu(Al) metallic glasses
Filip Kaskosz, Rene Alvarez-Donado, Mikko Alava +2
We investigate multi-component metallic glass systems using a hybrid Molecular Dynamics (MD) and Variance-Constrained Semi-Grand Canonical approach. This method enables us to gener…
Quasi-localized modes in crystalline high entropy alloys
Silvia Bonfanti, Roberto Guerra, Rene Alvarez-Donado +3
High Entropy Alloys (HEAs) are designed by mixing multiple metallic species in nearly the same amount to obtain crystalline or amorphous materials with exceptional mechanical prope…
Mechanisms of strength and hardening in austenitic stainless 310S steel: Nanoindentation experiments and multiscale modeling
F. J. Domínguez-Gutíerrez, K. Mulewska, A. Ustrzycka +7
Austenitic stainless steels with low carbon have exceptional mechanical properties and are capable to reduce embrittlement, due to high chromium and nickel alloying, thus they are…
Shear banding instability in \remove{high entropy} multi-component metallic glasses: Interplay of composition and short-range order}
Kamran Karimi, Amin Esfandiarpour, Rene Alvarez-Donado1 +2
The shear-banding instability in quasi-statically driven bulk metallic glasses emerges from collective dynamics, mediated by shear transformation zones and associated non-local ela…
Splitting up entropy into vibrational and configurational contributions in bulk metallic glasses: A thermodynamic approach
René Alvarez-Donado, Alex Antonelli
We applied an efficient methodology to separate vibrational and configurational entropies in bulk metallic glasses by means of molecular dynamics simulation based on a combination…
Revisiting the fragile-to-strong crossover in metallic glass-forming liquids: application to CuZrAl
René Alvarez Donado, Samuel Cajahuaringa, Alex Antonelli
The fragile-to-strong crossover seems to be a general feature of metallic glass-forming liquids. Here, we study the behavior of shear viscosity, diffusion coefficient and vibration…
