Microstructure-guided optimization of octahedral lattice structures for enhanced energy absorption via LPBF

Description

This dataset supports the experimental and microstructural analysis presented in the study titled “Microstructure-guided optimization of octahedral lattice structures for enhanced energy absorption via LPBF.” It includes raw and processed data from uniaxial compression tests, micro-computed tomography (Micro-CT), and scanning electron microscopy (SEM) performed on both initial and optimized Ti6Al4V lattice structures fabricated using laser powder bed fusion (LPBF). The repository also contains high-resolution figures, mechanical performance metrics, porosity analysis, original microscopy images, and defect quantification maps. These data are intended to support reproducibility, secondary analysis, and future modeling efforts in the field of additive manufacturing and architected materials.

Steps to reproduce

All lattice structures were designed using Creo Parametric and fabricated via LPBF using Ti-6Al-4V powder. Micro-CT scans were conducted using the AX-2000 micro-computed tomography (micro-CT) system for internal defect analysis. SEM imaging was performed on a tungsten filament scanning electron microscope (ZEISS, EVO 10, German). Compression tests were carried out on Servo hydraulic universal testing machine CMT-5100 at strain rate of 2 mm/min. Processed data and raw Origin files for stress–strain plots and SEA calculations are included.
