Modeling of Diffusion-Controlled Crystallization Kinetics in Al-Cu-Zr Metallic Glass
Round 1
Reviewer 1 Report
The authors presented modelling results of crystalization kinetics in bulk metallic glasses controlled by diffusion. Overall, the paper is well written, with a few typos, and the topic certainly is appropriate for publication in Metals. Therefore, I recommend the publication. A few comments follow:
On page 1, please show what is behind the achronym JMAK. I guess it is Johnson-Mehl-Avrami-Kolmogorov.
Maybe I missed the information, but what were the values of sigma_0 finally used in the simulations to compute the interfacial energy sigma? The same for the timestep delta_T used to integrate Eq. 20.
On page 12, when the authors say "At high cooling rates, transient nucleation effects (...)". Did they mean "At high heating rates (...)"?
In Table 2, where some simulation results were summarized, the experimental values should be present also in order to make easier the comparison.

Reviewer 2 Report
Modeling of crystallization processes in metallic glasses is a challenging task but it gives pivotal information for understanding the mechanisms of nucleation, growth, and dissolution of crystals in a system. This paper gives a comprehensive and detailed description of these processes under different conditions. The model results obtained agree satisfactory with experimental data available. The paper is well organized and gives a good overview of the issues considered. I recommend publishing it in the present form.

Thank you for acknowledging our work.
Reviewer 3 Report
This manuscript presents the modeling of diffusion-controlled crystallization kinetics in Al-Cu-Zr metallic glass. However, this manuscript needs significant work to be acceptable for publication. The following are the key points that need attention:
- Fe40Ni40P40B6 at% is not an accurate composition, P2, line
- How many exothermic peaks during the heating process on Al10Cu30Zr60metallic glass? Do these exothermic peaks correspond to CuZr2 or Al3Zr4 phase? How about 800K? Is there any experimental evidence for theses phases at this temperature?
