abstract = {In two-component metallic systems, thermodynamic immiscibility leads to phase separation
such as in two-phase eutectic compositional alloys. The limit of the immiscibility of
component elements under non-equilibrium conditions have been explored, but achieving
complete miscibility and formation of single phase microstructures in eutectic alloys would
be unprecedented. Here we report that during low-temperature ball milling that provides high
energy impact, complete mixing of phases can occur in immiscible Ag-Cu eutectic alloys.
From combined theoretical and experimental studies, we show that impact can produce solid
solutions of Ag-Cu nanoparticles of eutectic composition. Our results show that phase
diagrams of low dimensional materials under non-equilibrium conditions remain unexplored
and could lead to new alloy microstructures drastically different from their bulk counterparts.},

abstract = {Joining different parts is one of a crucial component of designing/engineering of materials. The current energy, low efficiency weight automotive and aerospace components commonly consist of different class of materials, such as metal, polymer, and ceramics, etc. Joining these components remains a challenge. Here, we demonstrate joining of metal (aluminum) and polymer (PP) using mechanical friction. The detailed characterisation demonstrates that atomically locked interfaces are formed in such joining without the presence of any chemical bond at the interfaces. The waterproof and strong interface is formed in such process. Fully atomistic molecular dynamics simulations were also carried out to provide further insights on these mechanisms.},
