Round 1

Reviewer 1 Report

The article is devoted to the study of structural evolution and transitions of mechanisms in creep deformation of nanocrystalline promising fuel cladding material (FeCrAl alloys). Creep is one of important mechanical properties of FeCrAl alloy used as fuel claddings under high temperature condition. This work aims to elucidate the deformation feature and underlying mechanism during creep process using atomistic molecular dynamics simulations. In this regard, the work seems to be relevant and important. Creep mechanisms and the main factors influencing them were studied in detail in this work. A large amount of work has been done.

            There are the following remarks.

  1. Figures 13-16 look great. However, it is desirable to explain the observed effects in more detail. If possible, make estimates of observed shifts, for example, with increasing temperature, based on hypothesized mechanisms (using formula (1)). Then it will be possible to compare the calculated estimates of displacements with those observed in the simulation.

The manuscript is recommended for publication with minor correction.
