1、Dear reviewers:ly,wereallyappreteyoursuggestionsontheprentitled“Characterization of High-strength Mg-Gd-Zn-Zr Alloys Developed by Differential-thermal Extru”, which we resubmitted for publicationhe MaterialsCharacterization. We have followed the advice and revised our manuscript and figures.Most of

2、the reviare marked in redhe manuscript and figures. The commentsfrom the two reviewers and our corresponding responses were listed as follows:-Reponses to Reviewer 1:1. The English writing of the p he text.Response: 这条不用管，r should be improved. There are some mistakes慢慢看2. Authors should avoid referr

3、ing to their obtained resultsheroduction part.Accordingly, the last part of theroduction should be revised.Response: 明哥，就是这一段要修改。3.

4、049.Response: We added the pr titled “An Unusual ExtruTexturegGdYZr Alloys” to be the 20th reference as it is also related to extru.4. Particles presented in Fig. 2 should beidentified experimentally, and thencompared with the results foundhe literature.Response: We added a new Figure after Fig. 2 w

Considering theextrupros rarely changes the phase comition of the sles for its shortduration, the particles are suggested to

The SAED pattern in Fig. 3a 33 shows theblocky particles have a face-center-cubic (fcc) structure wilattice constant of 0.72nm, which indicates the particles to be (Mg, Zn)3Gd phase 38-40. The EDS result of the particles in

7、Fig. 3c show the same results. Referring to the rod-like particles, the EDS result in Fig 3d indicate the particles are Zn-rich and Zr-rich phase. Furthermore,a lattice constant of 0.77 nm can be calculated based on the SAED pattern in Fig. 2b,whiatches the lattitructure of the Zn2Zr3 particle (tetr

This term usually apps to an annealing treatment after whichthe ssles are quenched for further heat treati

Here, the authors have cooled theirles after this treatment, and thus, it is suggested to call this treatment as“homogenization” instead of “Solutionizing”.Response: We replaced all the “solution-treated” by “homogenized”.6.

10、Response: 明哥，我实在看不出来这篇实验看出来了告诉我一声还有哪些地方要，明哥-Responses to Reviewer 21. As for the labels in Fig. 2, the authors should provide relevant eviden as XRD and EDS data.uchResponse: Thiggestion is similar to the 4th one of Reviewer 1. We added a newFigure after Fig. 2 which shows the TEM results of the par

The authors should provide high magnified images showing the morphologyof the existed LPSO phase.Response: We added a new figure (Fig. 4b now) wihigher magnification toshow the morphology of the LPSO structure. The TEM micrographs combined w

Only one is enough.Response: Fig. 7 shows the original represenive engineering curves of the les and the YS, UTS and elongation shown in Fig. 8 are obtained from Fig. 7.sTherefore, we think both of them are nesary. However, as both the figures are aboutthe tensile properties, we combined themo
