| Abstract Scope |
In this study we investigate the structural and thermodynamic properties of Cu64Zr36 metallic glass nanoparticles (MG NPs) using molecular dynamics simulations. By simulating NPs with diameters ranging from 1 to 20 nm, we examine their formation through a melt-quenching process using a relatively slow quench rate of 10ˆ9 K/s. Our results highlight size-dependent characteristics, such as surface segregation of Cu atoms and variations in thermal properties. Smaller NPs show increased copper icosahedral content, indicating enhanced strength and hardness. We also explore the thermal stability and glass transition temperatures, finding that larger NPs exhibit higher transition temperatures. Furthermore, the NPs generated are being used to construct realistic nanoglasses and gradient nanoglasses, which can be directly compared to those synthesized in experiments. These findings are crucial for optimizing the synthesis of gradient nanoglasses and provide valuable insights for the development of advanced heterogeneous metallic glasses with tailored properties for structural applications. |
