It is shown by computer simulation of the Al-Si solid solution that at the first stages of Si precipitates formation the small Si clusters arise in the tetrahedral configurations. This process is accompanied by the effect ...

Si precipitates formation in Al-Si alloys is a subject of many investigations. Al alloys are widely used as structural materials in nuclear reactors and have many other important applications.

We have applied molecular dynamics method and semi-empirical potential [1] to obtain the realistic picture of Si surface layers relaxation.The starting configuration was taken as a parallelepiped containing 864 atoms. There ...
