Merging of the grains during wire drawing

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.
