چکیده
Directed Energy Deposition Additive Manufacturing (DED-AM) is transformative for the production of larger, geometrically complex metallic components. However, mechanical properties titanium alloy DED-AM components do not always reach their full potential due to microstructural features including porosity and regions lack fusion. Using in situ operando synchrotron X-ray imaging we gain insights into key laser-matter interaction feature formation mechanisms during Ti-6242. Analysis process conditions reveals that laser power dominant build efficiency while higher traverse speed can effectively reduce fusion regions. We also elucidate underlying several physical phenomena occurring deposition alloys, a saddle-shaped melt pool pore pushing. The findings this work clarify transient kinetics behind alloys be used as guide optimising industrial additive manufacturing processes.
