Structure Relaxations during the Isothermal Annealing 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 metallic glass of Ca₇Mg₃ alloy is relaxed into amorphous structure of greater stability in which much more icosahedron structures is formed; interestingly, it is also found that the short short-range order has no change, while the short-range order of the system increases during the isothermal annealing process.
