Abstract Scope |
This research aims to improve lattice structures’ strength and energy absorption capabilities made from AM β-TI5553 alloy. This is achieved by optimizing the crystallographic texture and unit-cell geometry at the strut level. We use fast Fourier transform crystal plasticity simulations to identify the optimal microstructure for each strut orientation. To address the struts level plastic anisotropy and asymmetric tension-compression behavior observed in AM β-TI5553 alloy, the anisotropic CPB06 yield criterion is applied in macroscale finite element analyses of lattice unit-cells. This allows for determining yield surface parameters for each texture, enabling strut-level stress analysis. This integrated approach significantly enhances the mechanical properties of AM β-TI5553 lattice structures by evaluating and optimizing the interplay between unit-cell geometry and strut-level microstructure, ultimately leading to considerable improvements in performance. |
