| Abstract Scope |
Severe plastic deformation with predetermined strain gradient can be considered as a way for creating of metallic materials with gradient structures. Strain gradient through sheet thickness can be achieved by special cold rolling technique, when one of the work rolls has microscopic sine profile of the surface. Effects of the amplitude of the sine profile (100…500 µm) of work roll, initial sheet thickness (1…5 mm) and thickness reduction per pass (5…50%) on the material behavior and strain gradient through Al sheet thickness were analyzed by the finite element method with using software QForm 3D. The process parameters were found which could provide extremely high strain difference through sheet thickness. Finite element analysis of strain gradients, presented in this study, can be used for development of the special rolling techniques for fabrication of metal sheets with gradient structures, when the grain size changing from microns to nano-scale, and improved mechanical properties. |
