; Abstract: The kinetic Monte Carlo method, which based on the Multi-States Ising Model, was applied to simulate the effect.... In this model, "vacancy-locking" and "vacancy clusters" are two important mechanisms in the aging process. Key words: Al-Ag alloy; kinetic Monte Carlo method; microalloying elements; aging stage ......
in a TG experiment, a modern equipment typically registers hundreds or thousands of experimental points that can be used for kinetic analysis of the reaction.It is clear that the selection of correct model is a critical point in kinetic analysis. Knowing how a model can justify experimental data has been evaluated by many researchers[1-3]. There are different methods to study the kinetics of non......
