| Abstract Scope |
AlSi10Mg is the most widely additively manufactured and commercialized aluminum alloy. In this study, AlSi10Mg specimens were manufactured by selective laser melting process followed by post-process heat treatment at various temperatures. Microstructures were characterized by optical and electron microscopes and mechanical properties were studied by micro-indentation hardness and tensile tests. Various phases were analyzed by X-ray Diffraction (XRD) and Electron Probe Micro-Analyzer (EPMA) techniques. Observation shows that it’s nearly impossible to completely dissolve the evolved second phase silicon particles which may have significant effects on the mechanical characteristics. Back Scattered Electron imaging results show the evolution of iron-rich particles in the aluminum matrix which may have significant influence on the mechanical properties of the alloy. |
