Texture Evolution during Roll-Cladding of a Composite of Five Plies of Ferritic Stainless Steel and Aluminium Sheets
Abstract:
A clad composite of five plies of STS/Al/Al/Al/STS was produced by roll-cladding at 350°C from ferritic stainless steel (STS) and aluminum (Al) sheets. In order to clarify the strain state during roll-cladding, the evolution of textures at different through-thickness layers in the roll-clad composite was investigated. Because the deformation mainly occurred in the Al sheets during roll-cladding, the present investigation was focused on the Al sheets. In the STS/Al/Al/Al/STS composite, the mid Al sheets between STS and center Al displayed pronounced texture gradients with shear textures and plane strain rolling textures, while the center Al sheet depicted a plane strain texture throughout the whole sheet thickness. Simulations with the finite element method (FEM) disclosed that a large variation of shear strain rate during roll-cladding led to the formation of these texture gradients.
