Abstract Scope The aim of this study is to observe the effect of cooling rate and core-shell morphology on the mechanical properties of Ag-Cu-Ni based metallic systems using Hybrid Monte Carlo and Molecular Dynamics simulations. Model systems comprising mono (Ag, Cu, Ni), equiatomic binary (Ag-Cu, Ag-Ni, Cu-Ni) and ternary Ag-Cu-Ni metallic clusters were simulated under melting-quenching thermal process to get amorphous and polycrystalline core-shell structures. A theoretical treatment of the interatomic interactions was in good agreement with the phase transitions and melting temperatures. We used thermal process results in mechanical models that simulate similar conditions to compression and indentation processes to observe mechanical properties. By observing the deformed MD models and stress-strain relationships, we identified the effect of cooling rates, surface composition and core-shell morphology on mechanical properties and formability.
