Diffusion-less recrystallization at high uniaxial deformation

TL;DR

This study uses computer simulation to investigate how high uniaxial deformation causes diffusion-less recrystallization, leading to grain coarsening and specific grain structures in nano-wires.

Contribution

It reveals the mechanisms of diffusion-less recrystallization during high uniaxial deformation in nano-wires, highlighting the formation of distinct grain structures.

Findings

Coarsened grains with fewer defects form under uniaxial tension.

Tension results in crystal filament-like structures.

Compression leads to two grains disoriented at four degrees.

Abstract

It was shown by computer simulation that coarsened grains with lower content of defects are formed at uniaxial deformation of a four-grain infinite nano-wire. The structure similar to crystal filaments was formed in the case of tension. The case of compression demonstrated formation of two grains (from four initial one) disoriented at an angle of four degrees.
