Additive Manufacturing (AM) is a rapidly emerging class of techniques that involve synthesizing parts layer-by-layer. The creation of highly complex geometries with high dimensional precision and good surface integrity, in contrast to traditional manufacturing techniques which limit design freedom, enables AM processes to be desirable choices in industrial applications. Nonetheless, in order to attain desirable metal products, relationships between manufacturing methods, observed microstructures, and resulting mechanical behaviors must be contrasted. A material’s microstructure has a crucial impact on its mechanical properties due to the phase distribution and grains in the material itself. Furthermore, variations in metal additive manufacturing processes induce alterations in the microstructure of materials, thereby affecting the overall mechanical behaviors of their structures. Therein, this study focuses on the correlations between the microstructure and the tensile properties of an aluminum alloy (AlSi10Mg) fabricated through AM as compared to literature. Furthermore, the impact of heat treatment on the tensile behavior of AlSi10Mg is investigated with an emphasis on microstructure evolution.
