Round 1

Reviewer 1 Report

Thanks for sharing your results by this paper.

It would increase the value when some more information (not just literature references) would be given for instance:

- how composition was determined (fig. 2),

- on the calculations leading to fig.3.

For better readability figures shall be placed within the text where the topic is mentioned.

Page 3, line 85: Fig. 3 does not show calculations. It just shows calculated vapor pressures of single elements in dependence on annealing temperature.

Taking that as an example, please check the accuracy within the whole text.

Page 6, line 142: replace "on" by "in"

Reviewer 2 Report

In this draft the authors synthesized MoNbTaVW thin film and studied its properties at different annealing conditions. The manuscript provides some useful information to the class of high entropy alloys, and it can be published after revising the questions below:

  1. As the V content is kept almost constant under Ar annealing, what is the furnace pressure under Ar atmosphere?
  2. In Figure 3, as the furnace pressure changes during the annealing process, it’s not accurate to show the pressure range in a rectangle shape; it would be more accurate to plot the furnace pressure with regard to the temperature.
  3. The resistivity stays almost constant with temperature increase, has the authors considered the contribution of composition change to the resistivity?
