Controlling the Plastic Anisotropy of Magnesium Alloy by Tailoring the Grain Size and Yttrium Content

Round 1

Reviewer 1 Report

 

 

This manuscript proposed to the formability of Mg alloys can 20 be improved by combining the grain refinement and alloying approaches. The idea of the article and the author's work are both innovative, the paper is well organized, thus the article is suitable to be accepted and published in this journal after minor revision.

1. The details of the experimental method should be given, such as sample preparation, processing technology, tensile test parameters and equipment, etc.

 

2. Why 0.2, 0.6, 1.0 and 3.0wt.%Y these components were chosen, which can be explained in the introduction, is it related to the Mg-Y binary phase diagram, and does the Mg-Y second phase form and cause effects?

Reviewer 2 Report

The paper presents a modeling and numerical study on effects of Y-content on Mg alloys deformation and mechanical properties.  The results are consistent with the experiment and helpful for understanding of Y-alloying treatment of Mg alloys to improve their properties.   The following minor revisions are needed to be addressed before acceptance. 

1. Please strengthen the Discussion section, by providing more discussion on how Y-addition affects the parameters E, a and c, etc. and thus affect the deformation. 

2. Please clarify the input texture used in the four calculation cases.  Was one or four texture conditions used?   Y-addition would affect the casting and rolling process of Mg alloys, and different Y content would lead to different dynamic recrystallization in rolling/extrusion process and thus different textures. 

3. In Fig.3, the legends of the curves should be provided appropriately. 

4. What is the Y content range that the proposed model works for? Should it work only for Binary alloys?
