(Test Method)Standard Test Method for Analysis of Titanium Alloys by Wavelength Dispersive X-Ray Fluorescence Spectrometry
Standard Test Method for Analysis of Titanium Alloys by Wavelength Dispersive X-Ray Fluorescence Spectrometry
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.

4. Summary of Test Method
4.1 The specimen is finished to a clean, uniform surface and then irradiated by high-energy X-ray photons. Secondary X rays
are produced and emitted from the sample. This Using analyzing crystals, this radiation is diffracted by means of crystals and
focused on a detector, whichand directed towards a detector that measures the count rates at specified wavelengths. The output(s)
of the detector(s) is integrated or counted for a fixed time or until the counts reach a certain fixed number. Mass fractions of the
elements are determined by relating the measured radiation of unknown samples to calibration curves prepared using reference
materials of known compositions.
