ASTM B884-11

Standard Specification for Niobium-Titanium Alloy Billets, Bar, and Rod for Superconducting Applications

ABSTRACT
This specification covers three grades of zirconium and zirconium alloy forgings. The forgings shall be formed with conventional forging equipment normally found in primary ferrous and nonferrous metal plants. The forgings are furnished in three grades as Grade R60702, Grade R60702, and Grade R60705. Forgings shall be furnished in the annealed conditions. The material shall conform to the requirements as to chemical composition and tensile properties prescribed. Two tension tests shall be made from each lot. Two chemistry tests for hydrogen and nitrogen content shall be made from each lot of finished product. If the results of any tests of any lot do not conform to the requirements specified, retests shall be made on additional forgings of double the original number of the same lot, each of which shall conform to the requirements specified.
SCOPE
1.1 This specification covers niobium-titanium alloy billets, bars, and rods, at 46 to 48 % titanium. This material is used in the manufacture of wire for superconducting applications.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 The following precautionary caveat pertains only to the test methods portion, Section 14, of this specification: 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.
