Atomistic simulations of the interaction of basal dislocations with MgZn precipitates in Mg alloys
G. Esteban-Manzanares, R. Alizadeh, I. Papadimitriou +3
The interaction between Mg edge basal dislocations and rod-shaped -MgZn precipitates was studied by atomistic simulations using a new interatomic potential. The atomistic…
Basal dislocation/precipitate interactions in Mg-Al alloys: an atomistic investigation
Gustavo Esteban-Manzanares, Anxin Ma, Ioannis Papadimitriou +2
The interaction between edge basal dislocations and -MgAl precipitates was studied using atomistic simulations. A strategy was developed to insert a lozenge-shaped…
Mechanical behavior of InP twinning superlattice nanowires
Z. Liu, I. Papadimitriou, M. Castillo-Rodríguez +6
Taper-free InP twinning superlattice (TSL) nanowires with an average twin spacing of ~ 13 nm were grown along the zinc-blende close-packed [111] direction using metalorganic vapor…
Strengthening of Al-Cu alloys by Guinier-Preston zones: predictions from atomistic simulations
G. Esteban-Manzanares, B. Bellón, E. Martínez +2
A scale bridging strategy based in molecular statics and molecular dynamics simulations in combination with transition state theory has been developed to determine the flow stress…
Precipitation during high temperature aging of Al-Cu alloys: a multiscale analysis based on first principles calculations
H. Liu, I. Papadimitriou, F. X. Lin +1
Precipitation during high temperature aging of Al-Cu alloys is analyzed by means of the integration of classical nucleation theory and phase-field simulations into a multiscale mod…
Discrete dislocation dynamics simulations of dislocation- precipitate interaction in Al-Cu alloys
R. Santos-Güemes, G. Esteban-Manzanares, I. Papadimitriou +3
The mechanisms of dislocation/precipitate interaction were studied by means of discrete dislocation dynamics within a multiscale approach. Simulations were carried out using the di…
A multidisciplinary approach to study precipitation kinetics and hardening in an Al-4Cu (wt. %) alloy
A. Rodríguez-Veiga, B. Bellón, I. Papadimitriou +3
A multidisciplinary approach is presented to analyse the precipitation process in a model Al-Cu alloy. Although this topic has been extensively studied in the past, most of the inv…
