文摘
- •
The initial porosity of SLM Ti6Al4V was significantly reduced by applying a systematic processing strategy.
- •
Marginal applied energy densities - excessive or insufficient - lead to two different mechanisms of pore formation.
- •
The correlation between pore orientation, and morphology allowed revealing voids critical for mechanical performance.
- •
Process optimization should consider pore formation mechanisms besides overall porosity to achieve low-void microstructures.
