1.1 本规范涵盖了通过钛合金的全熔粉末床熔合加工进行部件的增材制造。使用这种加工方法制造的部件通常用于需要类似于锻造产品的机械性能的应用中。根据本规范制造的产品可能需要额外的后处理，如机加工、抛光等，以满足必要的表面光洁度和尺寸要求。 1.2 本规范旨在供额外制造的钛组件的购买者或生产者或两者使用，以定义要求并确保组件性能。 1.3 建议用户使用本规范作为获取满足委员会成员协商一致确定和修订的最低验收要求的组件的基础。 1.4 在采购订单中添加一个或多个补充要求可以满足更严格的用户要求，这些补充要求包括但不限于补充要求S1中列出的要求- S16。 1.5 以国际单位制表示的数值应视为标准。其他单元仅供参考。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers additive manufacturing of components via full-melt powder bed fusion processing of titanium alloys. Components made using this processing method are typically used in applications that require mechanical properties similar to wrought products. Products built to this specification may require additional post-processing in the form of machining, polishing, etc., to meet necessary surface finish and dimensional requirements. 1.2 This specification is intended for the use of purchasers or producers, or both, of additively manufactured titanium 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 committee members. 1.4 User requirements considered more stringent may be met by the addition to the purchase order of one or more supplementary requirements, which include, but are not limited to, those listed in Supplementary Requirements S1-S16. 1.5 The values stated in SI units are to be regarded as the standard. Other units are included only for informational purposes. 1.6 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.
