Abstract
The paper investigates the combined effect from the dendritic structure and grain orientation on the deformation behavior of the additively manufactured AlSi10Mg alloy. Micromechanical models comprising Al cells separated by a Si-rich eutectic network are constructed using the experimental data. The constitutive behavior of the Al phase is described in terms of the crystal plasticity to consider its crystallographic orientation. Intragranular stress and strain partitioning between Al and Si phases is analyzed numerically. The cellular dendritic structure is shown to be responsible for the anisotropy of mechanical properties of as-built Al-Si alloys.
