Jul 22, 2020 · Numerous studies were carried out on the microstructure and mechanical properties of additively manufactured AlSi10Mg. It is most commonly fabricated through LPBF, where a heat source is directed at a metal powder bed and selectively melts predefined cross-sections in a layer-by-layer manner . Microstructure evolution and thermal properties of an A correlation between microstructural evolution and changes in thermal properties is established. Advantages and tailoring of the thermal properties of additively built parts are discussed. Implications of these results are important for other additively manufactured components based on popular solution treatable alloys.
