Linking microstructure and processing defects to mechanical properties of selectively laser melted AlSi10Mg alloy

Here we analyse the relationship between the monotonic and cyclic behaviour of cylindrical AlSi10Mg (CL31 AL) samples fabricated by Selective Laser Melting (SLM) to the build direction, the presence of manufacturing defects (pores, voids, oxides, etc.) and the beneficial effect of post-processing – T6 and hot isostatic pressing (HIP) – treatments. Correlative Computed Tomography (X-ray tomography, optical microscopy, electron backscatter...
