| Abstract Scope |
This study aimed to investigate the evolution of the microstructure and mechanical properties of as-fabricated laser powder bed fusion (L-PBF) Ti-6Al-4V samples by introducing layerwise pre-heating or post-heating laser scans. Multiple laser scans, varying in power and scanning speed, were examined before the melting laser scan (pre-heating) or after it (post-heating). The analysis focused on microstructural features such as porosity, lattice structure, phases, and grain size, as well as the tensile response of the material. The results revealed the additional layerwise scans had a significant impact on reducing porosity by up to 98% when the additional scan was applied prior to the melting scan. Post-heating laser scan enhanced the material’s plastic deformation by up to 9%. Furthermore, these findings highlight the potential of layerwise heating strategies to improve the overall quality and performance of L-PBF Ti-6Al-4V components, thus paving the way for enhanced applications in various industries such as aerospace. |
