Merging of the grains during wire drawing

TL;DR

This paper demonstrates that during wire drawing, grains merge through a mechanism akin to recrystallization driven by mechanical impact, leading to grain refinement without diffusion.

Contribution

It introduces a new mechanism of grain merging during deformation that occurs without diffusion, expanding understanding of recrystallization processes.

Findings

Grain merging occurs during wire drawing.

Recrystallization can happen without diffusion.

Mechanism is driven by mechanical impact.

Abstract

It has been first proved the effect of grains merging during drawing deformation. This was done with example of producing a steel wire from rod manufactured by rolling with shear technology and was shown not only grain refinement but its merging as well. The result obtained in current work has fundamental importance; it reveals new mechanism of the "recrystallization" which takes place without diffusion actions owing to the mechanical impact.
