Formation and Evolution of Icosahedron during Relaxation of Amorphous Ca₇Mg₃ Alloy

Abstract:

The molecular dynamics simulation studies on the microstructure evolution properties of amorphous Ca₇Mg₃ alloy during the isothermal annealing have been performed. The simulated structure factor S(q) of Ca₇Mg₃ is well agreed with the experimental data. Results indicate that the icosahedron structure plays dominate role in the structure transformation, and the smaller Mg atoms are much more probable to be the central atoms of the basic clusters of icosahedron.
