摘要

1.1This specification covers powder metallurgy (PM) structural components fabricated from:1.1.1Commercially pure (CP) (that is, unalloyed) titanium powder,1.1.2Pre-alloyed powders.1.1.3Mixtures of elemental powders or mixtures of elemental powders and pre-alloyed powders.1.2This specification covers:1.2.1Grade 1 PM—Unalloyed titanium,1.2.2Grade 2 PM—Unalloyed titanium,1.2.3Grade 3 PM—Unalloyed titanium,1.2.4Grade 4 PM—Unalloyed titanium,1.2.5Grade 5 PM—Titanium alloy (6 % aluminum, 4 % vanadium),1.2.6Grade 9 PM—Titanium alloy (3 % aluminum, 2.5 % vanadium),1.2.7Ti-6Al-4V PM Low Interstitial (LI),1.2.8Ti-6Al-6V-2Sn PM.1.3The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.1.4This 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.1.5This 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. 1.1本规范涵盖由以下材料制成的粉末冶金（PM）结构部件:1.1.1商用纯（CP）（即非合金）钛粉，1.1.2预合金粉末。1.1.3元素粉末的混合物或元素粉末和预合金粉末的混合物。1.2本规范涵盖:1.2.11级PM-非合金钛，1.2.22级PM-非合金钛，1.2.33级PM-非合金钛，1.2.44级PM-非合金钛，1.2.55级PM-钛合金（6 % 铝，4 % 钒），1.2.69级PM-钛合金（3 % 铝，2.5 % 钒），1.2.7Ti-6Al-4V PM低间质（LI），1.2.8Ti-6Al-6V-2Sn粉末冶金。1.3以国际单位表示的数值应视为标准值。本标准不包括其他计量单位。1.4本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。1.5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。展开▼
