Thermodynamic and structure evolution of Aluminum nanoparticle with diameter of 10 nm are investigated due to heat treatment by means of stepping heat and compared it to sudden heat. Molecular Dynamics (MD) simulation is employed to track the trajectories of each atom and its surrounding to define thermodynamic properties, e.g., temperature and pressure. The temperature evolution gives clear different profile for both cases, while pressure profile strongly evident different mechanism of melting. From thermodynamics point of view, the nanoparticle suffered different final state for both heating methods. Structure analysis later confirmed that for stepping heat the nanoparticle is melted while for sudden heat it is only partially melted. © Content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence
