【国外标准】 Standard for Additive Manufacturing – Post Processing Methods – Standard Specification for Thermal Post-Processing Metal Parts Made Via Powder Bed Fusion

This specification covers the requirements for thermal post-processing of parts produced via metal powder bed fusion to achieve the required material properties and microstructure to meet engineering requirements. It currently applies to thermal post-processing for alloy titanium-6 aluminium-4 vanadium, alloy titanium-6 aluminum-4 vanadium extra low interstitial, and commercially pure titanium (CPTi); cobalt-28 chromium-6 molybdenum; alloy UNS N07718; alloy UNS N06625; alloy UNS S31603; alloy AlSi10Mg; cobalt 28 chromium 6 molybdenum; alloy UNS N07718; alloy UNS N06625; alloy UNS 31603; and alloy AlSi10Mg. Applicable parts covered in this specification include, but are not limited to, the manufacture of medical implants, aerospace parts, critical parts for power generation and oil and gas production. This specification should also be applied to test specimens used to generate design data for part material properties.1.1 This standard specifies the requirements for thermal post-processing of parts produced via metal powder bed fusion to achieve the required material properties and microstructure to meet engineering requirements. This standard is intended to be referenced by Material Part Property specifications for powder bed fusion. Currently, this standard includes thermal post-processing for the materials including titanium alloys, cobalt 28 chromium 6 molybdenum, alloy UNS N07718, alloy UNS N06625, alloy, UNS 31603 and AlSi10Mg. This specification will be updated as new powder bed fusion material heat treatments are developed.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
