Standard Specification for Additive Manufacturing Titanium-6 Aluminum-4 Vanadium ELI (Extra Low Interstitial) with Powder Bed Fusion

ABSTRACT
This specification establishes the requirements for additively manufactured titanium-6aluminum-4vanadium with extra low interstitials (Ti-6Al-4V ELI) components using full-melt powder bed fusion such as electron beam melting and laser melting. The standard covers the classification of materials, ordering information, manufacturing plan, feedstock, process, chemical composition, microstructure, mechanical properties, thermal processing, hot isostatic pressing, dimensions and mass, permissible variations, retests, inspection, rejection, certification, product marking and packaging, and quality program requirements.
SCOPE
1.1 This specification covers additively manufactured titanium-6aluminum-4vanadium with extra low interstitials (Ti-6Al-4V ELI) components using full-melt powder bed fusion such as electron beam melting and laser melting. The components produced by these processes are used typically in applications that require mechanical properties similar to machined forgings and wrought products. Components manufactured to this specification are often, but not necessarily, post processed via machining, grinding, electrical discharge machining (EDM), polishing, and so forth to achieve desired surface finish and critical dimensions.  
1.2 This specification is intended for the use of purchasers or producers or both of additively manufactured Ti-6Al-4V ELI components for defining the requirements and ensuring component properties.  
1.3 Users are advised to use this specification as a basis for obtaining components that will meet the minimum acceptance requirements established and revised by consensus of the members of the committee.  
1.4 User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which may include, but are not limited to, those listed in S1-S4 and S1-S12 in Specification F2924.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
