Significance and Use
5.1 This method is suitable for providing data on the chemical composition of titanium alloys having compositions within the scope of the standard. It is intended for routine production control and for determination of chemical composition for the purpose of certifying material specification compliance. Additionally, the analytical performance data included with this method may be used as a benchmark to determine if similar X-ray spectrometers provide equivalent precision and accuracy.
5.2 Compositions outside the ranges in 1.1 may be reported if proper method validation is performed. Refer to Guide E2857 for information on method validation.
1. Scope
1.1 This test method2 covers the X-ray fluorescence analysis of titanium alloys for the following elements in the ranges indicated:
| Element | Range, % |
| Aluminum | 0.041 to 8.00 |
| Chromium | 0.013 to 4.00 |
| Copper | 0.015 to 0.60 |
| Iron | 0.023 to 2.00 |
| Manganese | 0.003 to 9.50 |
| Molybdenum | 0.005 to 4.00 |
| Nickel | 0.005 to 0.80 |
| Niobium | 0.004 to 7.50 |
| Palladium | 0.014 to 0.200 |
| Ruthenium | 0.019 to 0.050 |
| Silicon | 0.014 to 0.15 |
| Tin | 0.017 to 3.00 |
| Vanadium | 0.017 to 15.50 |
| Yttrium | 0.0011 to 0.0100 |
| Zirconium | 0.007 to 4.00 |
