The Effect of the Shear Flow on the Morphological Pattern of Particles in an Undercooled Melt

Round 1

Reviewer 1 Report

The manuscript focused on the metal's grain deformation using undercooled melt. They also derive the asymptotic solution for the particle's mathematical model by employing the asymptotic technique. Very good work and I recommend the work to be published in the metal journal after making the required minor comments

·       The introduction should be enhanced with recent articles  for 2022, 2020, and 2021

·       The authors should add an extra paragraph in the introduction section to explain and compare the previous work and the current method

·       The English language of the manuscript contains some errors. I see it  should be revised using expert services

Reviewer 2 Report

The manuscript presents original theoretical results of solving the problem of crystallization in a moving undercooled melt. The authors obtained an analytical solution of the problem and its asymptotic form, which made it possible to investigate the effect of the shear flow velocity on the growth of solid particles formed in a convective melt. The results obtained showed that the shear flow in the undercooled melt intensifies the deformation and distortion of the formed solid-phase particle at the initial stage of crystal growth. The most important result of this study is the prediction of the possibility of the formation of small crystalline particles in an undercooled melt flow with an increase in the shear rate in the flow. The formation of small particles of the primary crystalline phase (caused by the shear effect in a specially created undercooled melt flow) can significantly strengthen the alloy obtained as a result of crystallization. The authors put forward the assumption that smaller particles of the second phase in the convective flow of the melt can be embedded between micron-sized grains.

The quality of the manuscript could be improved.

 1) It is necessary to indicate more specifically the limits of applicability of the obtained solution.

 2) It is desirable to present a comparison of the grain structure parameters predicted on the basis of the solutions of the problem obtained by the authors and experimental data. 

Such a comparison should demonstrate the adequacy of the assumptions made by the authors when obtaining solutions and the predictive ability of the solutions obtained.

1   3) There is a typo (in word “undercooled” ) in the title of the manuscript.
