Descrição: In this work, grain-scale simulations of the deformation behavior of an AlSi10Mg alloy produced by selective laser melting are performed. The simulations involve the development of geometrical models of Al-Si eutectic and α-Al dendritic structures with an explicit account of the microstructural features. Finite-element calculations of uniaxial tension of the model microstructures are carried out. The stress and strain fields developing in the Al-Si eutectic and α-Al dendritic structures are analyzed. The stress–strain curves are calculated to obtain a homogenized response of the materials under study.
