Resistance of Heterogeneous Metal Compositions to Fracture under Dynamic and Cyclic Loads
Round 1
Reviewer 1 Report
Comments and Suggestions for Authors
This paper presents the results of experimental data analysis, which indicate an increased resistance of heterogeneous multilayer clad composites to dynamic loading destruction compared with homogeneous materials. The main problems are as follows：
1 Too many keywords, reduce to less than 5 keywords;
2 The experimental method needs to introduce the experimental materials, components and basic mechanical properties;
3 Figures 1 and 2 are the results of the author's own experiments, also Is there a citation?
4 On line 190, how to use the unit of MPa for hardness? What does that mean?
5 The caption of Figure 3 is not standard, what are the figures a and b respectively, and the meaning of symbols is explained in the text;
6 The results section suggests adding microscopic images;
7 Add the 1, 2, and 3 labels in Figure 5

Dear... Reviewer 1's comments have been processed. We look forward to further comments from reviewers 2 and 3. Based on review #1 Thank you for your constructive comments; based on your recommendations, the following has been done: 1. Keywords have been shortened. 2. Added basic mechanical properties and compositions of materials in the experimental part. 3. Figures 1 and 2 are the results of the author’s team’s own experiments. 4. Microhardness in some cases is measured and expressed in MPa units. If necessary, we can send the relevant links. 5. We also tried to improve the quality of presentation of the article in English. 6. A publication is being prepared dedicated to these studies, which are currently ongoing. This article will present images of macro and microstructures of the materials under study. 7. Tags added. In addition, due to the recommendations of the editors, we decided not to publish Figure 5 in this article.

Reviewer 2 Report
Comments and Suggestions for Authors
The paper under review explores the improved resistance of heterogeneous multilayer clad composites when subjected to dynamic loading, contrasting them with homogeneous materials. The primary mechanism behind this enhanced resilience is identified as crack retardation arising from layer lamination at the boundaries of the composite materials.
While the research presented in the paper is interesting, there are some concerns regarding its structure and overall clarity. To enhance the quality and readability of the paper, the following suggestions are offered:
1. Clearer Introduction: The paper lacks a well-defined aim or objective in the Introduction section, despite conducting a comprehensive literature review. It is crucial to clearly state the paper's objectives and what the research intends to achieve.
2. Novelty and Literature Review: The article could benefit from a more explicit discussion of its novelty concerning the existing literature, especially concerning previously published works in the same field. Highlighting the unique contributions of this research in comparison to prior studies is essential. The recommended supplementary references from below should be included in the literature survey.
3. Detailed Test Information: A separate table summarizing all the tests conducted, including sample structures, compositions, and graphical images, should be included. This will provide readers with a clear and concise overview of the experimental data.
4. Revised Paper Structure: The structure of the paper could be improved by reorganizing it into the following sections: Introduction; Materials (including sample preparation and properties); Testing Methods; Results; Discussions; and Conclusions. This restructured format will enhance the paper's flow and accessibility.
5. Evidence and References: The paper currently relies heavily on verbal descriptions and explanations without providing concrete evidence or appropriate references, such as SEM (Scanning Electron Microscopy), EDS (Energy Dispersive X-ray Spectroscopy), XRD (X-ray Diffraction), or other analytical techniques. It is advisable to support the findings with empirical data and references. For instance, a lack of SEM images and EDS analysis to confirm the presence of tungsten carbides along grain boundaries weakens the paper's credibility.
6. Original Contributions: The paper reproduces Figure 5 from previous works without making clear the specific contributions of the authors to the field's existing knowledge. Authors should elucidate what distinguishes their research from prior studies and clarify their unique insights.
In summary, the paper holds promise in shedding light on the resistance mechanisms of heterogeneous multilayer clad composites to dynamic loading. However, the clarity and quality of the paper can be significantly improved by addressing the aforementioned issues and providing concrete evidence to support the findings. This will enhance the paper's value and make it more accessible to a wider audience.

Thank you for your constructive and helpful comments. We believe this will greatly help improve the standard of our publication. We would like to inform you about changes related to your proposals: 1. The purpose of the work has been adjusted. 2. Added material about the novelty of the research presented in the article. Some recommended links have also been added. 3. The article included Tables 1 and 2, which present data on the compositions and mechanical properties of the materials under study. 4. The structure of the article has been adjusted in accordance with your recommendations. 5. We completely agree with this comment. The lack of metallographic research results affects the evidentiary level of the presented materials. This article focused on the macrostructural characteristics and factors affecting the resistance of layered compositions to various types of loads. The authors plan to present the results of microstructural studies on this topic in the form of a separate article. At the moment, work on this publication is close to completion. 6. Figure 5 was in the previous version of our article; it is missing in the current version.
