Abstract
There are provided reactive metal powder atomization manufacturing processes. For example, such processes include providing a heated metal source and contact the heated metal source with at least one additive gas while carrying out the atomization process. Such processes provide raw reactive metal powder having improved flowability. The at least one additive gas can be mixed together with an atomization gas to obtain an atomization mixture, and the heated metal source can be contacted with the atomization mixture while carrying out the atomization process. Reactive metal powder spheroidization manufacturing processes are also provided.

1-188. (canceled)
A reactive metal powder atomization manufacturing process comprising:
- atomizing with an atomizing gas a heated reactive titanium alloy source to produce a raw reactive metal powder of titanium alloy particles, wherein atomizing the heated reactive titanium alloy source comprises intermittently injecting an additive gas to impart a component from the additive gas on particles of the raw reactive metal powder, the raw reactive metal powder comprising a powder having a particle size distribution of 10 to 53 micrometers with a flowability less than 40 s, measured according to ASTM B213.
