Process Requirements for Production of Powder Feedstock for use in Laser Powder Bed Additive Manufacturing of Aerospace parts
This material specification will cover both the production of precursor Ni base 625 powder feedstock for material to be used in the manufacture of aerospace parts under SAE Aerospace Standard AMS7000. This process/practice specification is necessary to define standard practices for topics that may include training, powder handling, process cleanliness, process environment, packaging, storage, shipping, material changes, traceability, calibration, maintenance, etc. This specification is to be production process agnostic and non-prescriptive.
Rationale: The Aerospace Material Specification is intended to provide the process requirements for production of Ni-base 625 precursor powder for use in production of aerospace parts via the laser powder bed additive manufacturing process. No such specification currently exists.
