Abstract

In this work an amorphization transition driven by grain size reduction in nanocrystal binary solid solutions is reported. From extensive molecular dynamics simulations, it is found that an amorphous phase is formed when the grain size is reduced to several nanometers in the nanocrystals made of solid solutions below their critical solute concentration. A phase diagram describing the crystal-to-glass transition is constructed and a Ginzburg-Landau theory is developed to elucidate the simulation results.
