Study of Tensile Strength of Aluminum Alloy Caused by Pulsed Laser Drilling

Round 1

Reviewer 1 Report

Heyan Gao et al., elaborated the manuscript “Study of tensile strength of aluminum alloy caused by pulsed laser drilling”. Important studies regarding the optimization of parameters relevant to nano and millisecond laser drilling were carried out, followed by yield strength, fracture morphology and elongation measurements. Generally, the structure of the manuscript is well established and English is used accordingly with minor misspell. Thus, I suggest a minor revision of the manuscript taking into consideration the following punctual observations:

-          Authors should rigorously correct the manuscript by removing unnecessary information that is contained in the template; For example: what is the type of paper?, remove words such as “affiliation 1, affiliation 2 etc.”; Remove guideline paragraph as: “This section may be divided by subheadings. It should provide a concise and precise description of the experimental results, their interpretation, as well as the experimental conclusions that can be drawn.”

-          Affiliation 2 should include also the department/laboratory;

-          Abstract should better express the motivation of the study (especially its application) and the main output of the results; what could gain the R&D from the presented results;

-          Only as an observation, authors should avoid using very old references;

-          The first paragraph from section 2 presenting relevant parameters of the laser and experimental setup could be better organized in a table;

-          Please add XYZ coordinates in figure 1 a and b;

-          In section 2, authors should include more information relating to the aluminum alloy (composition etc.); This is available also for the SEM instrument;

-          “In order to facilitate the study of the effect of ablation holes on strength, the ablation area is also normalized by defining the cross-sectional area of the ablation holes as the ablation area, normalizing the ablation area to obtain the ablation area ratio, and the ablation area ratio is calculated as follows:…” – reformulate, try to use abbreviations;

-          Add scale to Figure 5;
