摘要

Two composites of five plies of STS/Al/Al/Al/STS and STS/Al/STS/Al/STS were produced from ferritic stainless steel (STS 430) and aluminum alloy (AA 3003) sheets by roll-cladding at elevated temperature. In order to analyze the strain states during roll-cladding, the evolution of crystallographic textures at different through-thickness positions in the roll-clad composites was investigated. The finite element method (FEM) was employed to simulate the co-deformation of the different sheets and to determine the stresses and strains acting in the five-ply composites during roll-cladding. The strain states derived from the FEM simulations were used to model the texture evolution in the individual sheets of the roll-clad composites. Friction conditions were determined in a parametric study by fitting the overall thickness strains and modeled textures to the results obtained experimentally.
