Mapping the geometry of Ti-6Al-4V: from martensite decomposition to localized spheroidization during selective laser melting

The influence that complex component geometries can have on microstructure formation is investigated in a rocket engine impeller fabricated of a Ti-6Al-4V alloy by selective laser melting (SLM). The SLM melt pool monitoring, indicative of the component's thermal history during processing, is li...
