Abstract :
[en] As an easily processable Al alloy, AlSi10Mg manufactured by Laser Powder Bed Fusion (LPBF) has received a lot of attention so far. However, it is well known that microstructural heterogeneities at the scale of the melt pool – in particular the weaker Heat Affected Zone whose microstructure evolves during the deposition of the next layer – exert a strong detrimental effect on the ductility of AlSi10Mg LPBF. In this work, a 2D Finite Element (FE) model is developed in order to tackle this issue and help in guiding the optimisation of LPBF process parameters. The model is calibrated using experimental measurements of the melt pool height. Furthermore, to allow for the efficient simulation of 5 successive layers, a remeshing procedure is implemented. No heat accumulation is observed during the deposition of these 5 layers. The thermal history of the HAZ can thus be studied with a thermal model for one layer.
