Abstract

The article presents a mathematical model of grain evolution and dislocation density during cold asymmetric rolling of pure Al 99.5% aluminum and 7075 alloy. The effect of equivalent and shear strain on the aluminum alloy structure has been found. Convergence of simulation results and experimental information has been demonstrated.

Keywords

Aluminum, asymmetric rolling, shear strain, mathematical simulation, severe plastic deformation, grain size, dislocation density.
