Direct Current Annealing Modulated Ordered Structure to Optimize Tensile Mechanical Properties of Co-Based Amorphous Metallic Microwires

Round 1

Reviewer 1 Report

·       Line 118 : mistype “FORTUN language programming”,   should be:   “programming language Fortran”.   Please specify which exactly approach was used for the calculations and how does it work, it should be supported by references as well

·       Annealing process description is missing? Why exactly those current values were selected? Is it defined by the selected material?

·       Figure4 and 5 might be combined in one

·       Line 220-224:  the Weibull modulus explanation should be given in more scientific way

Reviewer 2 Report

The reviewed paper titled “Direct current annealing modulated ordered structure to optimize tensile mechanical properties of Co-based metallic microwires” is of a high scientific level.  The direct current annealing on the wire properties was demonstrated. In my opinion, it is suitable for publication in Metals.

 

The authors did not avoid minor errors and inaccuracies. Notes for reflection and minor correction of the work:

 

1. Introduction - in the introduction, it is worth mentioning the dimensions of the described micro-wires. Probably the authors know, but the readers do not necessarily

 

2. Materials and Methods:

-  no table with the chemical composition of the wire

- no wire dimensions and test specimens are given

 

3. Results and discussion -  in general, this part of the work is relatively well described

 

4. Conclusions - very well-written conclusions, to the point

Reviewer 3 Report

Dear Authors,

I came into the paper entitled "Direct current annealing modulated ordered structured to optimize mechanical properties of Co-based metallic microwires. The article is well written and structured and results are interesting. I recommend this article for publication as soon as some minor revisions are performed. Hereafter are my comments/questions/suggestions.

1/ I would suggest to the authors to add the word amorphous in the title of the paper. Indeed, crystalline cobalt alloys exist and it's important to the reader to quickly know about the kind of alloys under investigation here.

2/ the objective description of this paper could be improved. The sentence (p2, l56-57) is too vague.

3/ Why did you choose this specific chemical composition ? Is there any scientific or industrial interest ? This point must be specified.

 

4/ p2, l55, citations [18,19] are separated from the text by a point which must be removed.

 

5/ the description of the tensile test procedure is not enough. Wire testing is not straightforward and details are missing in the text. For instance, what is the load cell capacity ? What is it’s resolution ? How strains were measured ? What kind of glue was applied ? What is the expected strain rate ? I recommend the authors to add a schematic view or a picture of the tensile device. By the way, could the conclusions of the article changed by a increase/decrease in strain rate ?

 

6/ Why did you choose to increase the temperature by a direct current annealing ? How was applied the current : directly on the tensile specimen or on a large wire which is then cut to produce tensile specimens ? This information is missing.

 

7/ Can the conclusion of the article changed if a conventional high vacuum heat treatment is performed ? Is there any current assisted cluster formation ?

 

8/ p4, l135 : the term “wonderful” is not really scientific. Did the authors mean “defect free “?

 

9/ few words and references about the ACF could help the reader to better understand how to interpret results from figure 3. Indeed, some readers confortable with HRTEM may not be aware of those functions.

Reviewer 4 Report

(Review reports attached).

I have read the above mentioned manuscript by Wang et al. The manuscript describes DC current annealing of Co-based microwires and its effect on tensile and fracture properties. The manuscript [t is well written and the presented results are of importance to the research field. Hence, I recommend publication of the manuscript, after a minor revision with respect to the following points.

 

1) Page 2, first paragraph: please expand the abbreviation GMI

2) Section 3.1: Programming language will be Fortran.

3) Section 3.1: Please provide the mathematical equation, which was simulated to obtain the time temperature transient graphs.

4) Why two different SEM were used? The data is from Phenom Pro?

5) In pages 9-10, after explaining the effect of nano-cluster regions on shear band, the authors should correlate the decrease in tensile properties with this phenomena.

6) The manuscript shall be revised carefully, to correct a few grammatical errors.
