| Abstract Scope |
This presentation outlines our innovative approach to optimizing LPBF parameters to enhance the dynamic mechanical properties of AlSi10Mg, which is crucial for aerospace and automotive applications. We examined the effects of key LPBF parameters and post-processing thermal treatments on the alloy's performance under compression, tension, and shear loading. Advanced characterizations were used to study crack nucleation, propagation, and shell-to-core interactions, understanding their roles in transitioning the material's behavior from anisotropic to isotropic.
By integrating experimental methods with computational simulations and utilizing the Taguchi design of experiments, we identified and optimized critical parameters, providing valuable insights for engineers. Our findings reveal that specific LPBF parameter combinations followed by optimized thermal treatments can significantly reduce crack propagation, enhance isotropic behavior, and improve the alloy's dynamic strength. This study emphasizes the potential for innovative applications, revolutionizing the aerospace and automotive industries. |
