Simulation study on transition mechanisms of microstructures during forming processes of amorphous metals

摘要

For the first time, a molecular dynamics simulation study of 50000 atoms has been performed for the transi- tion mechanisms of the microstructure configurations of liquid metal Al during forming processes of amorphous state by rapid cooling. Not only have various bond-types been researched, but also icosahedra, defective icosahedra and Frank- Kasper polyhedra cluster structures were discussed.
