摘要

Lattice structures have gained an important place in engineering fields such as automotive, aerospace, and biomedical with the development of additive manufacturing technologies thanks to their high stiffness-to-weight ratio and topological diversity. AlSi10Mg alloy, which is widely used in these structures, attracts attention with its suitability for complex geometries and good mechanical properties. However, studies on performance-oriented optimization of lattice cell topology and geometric dimensions suitable for this alloy are limited in the literature. In this study, the optimum design parameters for basic lattice cells manufactured with AlSi10Mg are systematically investigated by using finite element analysis and bending tests. Based on the yield strength of the alloy, the optimum cell topology and dimensions are determined in finite element analyses, followed by verification by experimental tests and comparison of the results with the literature. In addition, the effects of heat treatment of AlSi10Mg alloy at phase transformation temperature on the mechanical strength and geometrical stability of lattice structures were investigated, and important findings were obtained regarding the role of this interaction on design and performance. In this context, the study proposes a holistic approach toward an optimized design and manufacturing process for AlSi10Mg-based structures.
