Characterization of Hot Deformation Behavior and Processing Maps of Mg-3Sn-2Al-1Zn-5Li Magnesium Alloy
Round 1
Reviewer 1 Report
The paper is an interesting study but requires a few amendments.
The introduction begins with “Magnesium alloy, the lightest structural metallic material, has been increasingly used in vast fields of telecommunication, automobile, medical machinery, aviation and aerospace, rail transit and so on”. This statement is not supported by any evidence. Based on sales volumes of magnesium producers over the last several years this statement is most likely false. If this statement is in fact true then the authors need to provide evidence.
In the Experimental Procedure the authors only describe casting, machining and heat treatment. However, in line 84 on page two they mention extrusion direction. Were the samples extruded? If so then the conditions need to be described.
The microstructures of the deformed alloy are shown in Fig 6. The pre deformed microstructure also needs to be included for reference and the phases present in the microstructure should be identified.

Reviewer 2 Report
The authors must to present the differences between the graphs from figure 1: they are different and some of them, (b), presents some unusual peak which must to be explained. Otherwise is useless to present all four graphs.
Figure 6 must to be explained entirely. It has no scientific content without explainig (b) and (d) and make some correlations.
Figure 10: why TEM analysis while the scale is microns? Why was necessary some amount of expenses. What do you want to show. Is unclear!
Conclusion no. 4 is only an observation. It must to be scientifically explained.
