Reviewer 2 Report
The manuscript entitled: Fixed and variable temperature SLPS of high chromium cast Fe with 25 wt.% Cr and its microstructure deal with hypereutectic high Cr cast Fe fabricated by two different SLPS . A systematic study on densification, microstructure, mechanical property and wear resistance were studied systematically.
Concerns with the present manuscript:
- A strong scientific discussion connecting fixed temperature SLPS and variable temperature SLPS w.r.t carbide formation and microstructure is missing
- There are lots of unindexed peaks in Fig. 6. All the peaks need to be indexed. If unknown, it should be marked unknown
- Error bars should be introduced for data points in Fig. 2(c), Table 5
- The test written inside Fig. 4(d) is barely readable
- Typos should be rectified. For instance, space should be introduced between number and unit. For example, 100nm should be written as 100 nm. It also applied for the scale bars in Figure.

Reviewer 3 Report
This paper is about a hot topic. The results obtained by the authors are interesting and may be useful to specialists. Therefore, I believe that this paper can be published.
However, the text presented could be significantly improved.
1. Tables.
The information in tables 1 and 2 can and should, in my opinion, be presented not in the form of tables. Why a table (table 2) tell about three numbers?
Tables 4 and 5 are best combined into one.
2. Thermodynamic modeling.
Figure 5 shows the results of thermodynamic modeling. But the text does not describe how this was done. The authors write "Phase diagram calculation analysis for the alloy is also performed by the authors as shown in Fig.5." This is not enough! What program are they using? I can guess that this is Thermo-Calc, but it needs to be said in the text. What databases are used? What are their versions? A lot depends on this!
What was the composition of the metal that was specified in the simulation? The result depends on this.
It is impossible to agree with the statement "It manifestes that the increase of carbide amount companys reduced both carbon and chromium solubility in the matrix as temperature drops gradually during solidification." Rather, a decrease in the solubility of these elements leads to an increase in the proportion of carbides.
Finally, the authors call it a "phase diagram" but it is not a "phase diagram" (although these are the results of thermodynamic calculations - they are not the same thing!).

No further remark.
Reviewer 2 Report
The authors have addressed the comments satisfactorily. However, the English language needs attention, which may be taken care of during the Editorial process I guess. Hence, the manuscript may be accepted for publication in the present form.
