1. Scope
1.1 This specification covers powder metallurgy (PM) structural components fabricated from: 1.1.1 Commercially pure (CP)(that is, unalloyed) titanium powder, 1.1.2 Pre-alloyed powders, and 1.1.3 Mixture of elemental powders or mixture of elemental powders and pre-alloyed powders. 1.2 This specification covers: 1.2.1 Grade 1 PMUnalloyed titanium, 1.2.2 Grade 2 PMUnalloyed titanium, 1.2.3 Grade 3 PMUnalloyed titanium, 1.2.4 Grade 4 PMUnalloyed titanium, 1.2.5 Grade 5 PMTitanium alloy (6 % aluminum, 4 % vanadium), 1.2.6 Grade 9 PMTitanium alloy (3 % aluminum, 2.5 % vanadium), 1.2.7 Ti-6Al-4V PM Low Interstitial (LI), and 1.2.8 Ti-6Al-6V-2Sn PM. 1.3 Units-The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
There is no PM standard for titanium components made from the range of commercially pure metals and alloys currently available. Approach will cover the use of pre-alloyed as well use of the blended elemental method.
