Oxygen, Nitrogen, and Hydrogen in Refractory Metals
Summary
Oxygen and nitrogen are alloying elements in titanium, and are also classified as alpha stabilizing elements as they promote alpha phase alloys. Interstitial oxygen and nitrogen levels can be used to regulate the tensile strength of the material, but due to its high solubility can cause unwanted surface embrittlement. This phenomenon can be leveraged,however, under controlled processing to create surface films that increase surface hardness and wear properties.

Procedure – Powder/Chip Samples
Instrument calibration/drift correction.
Add approximately 0.05 g of *** Graphite Powder to a***Graphite Crucible.
Firmly place the crucible on the lower electrode tip or appropriate autoloader position.
Press the Analyze button on the instrument screen,the lower electrode will close and the analysis sequence will start and end automatically.
Repeat steps 3b through 3i a minimum of three times for each calibration/drift standard used.
Procedure - Solid Samples
Determine the instrument blank.
Repeat steps 2b through 2g a minimum of three times.
Set the blank following the procedure outlined in the operator's instruction manual.
Instrument calibration/drift correction.
Login a minimum of 3 Standard replicates.
Weigh approximately *** grams of a calibration/drift standard, enter the mass and standard identification into appropriate replicate fields.
Note: LECO Reference Materia***o not require preparation.See preparation statement on the reference material certificate.

Method Selection
Two methods are described in this application note; either method can be used to analyze iron, steel, nickel-, and cobalt-base alloys. The Precision Method is recommended for general use and will provide the best precision and accuracy throughout the typical O, N, and H concentrations found in this group of metals; approximate cycle time is 3.5 minutes. The Fast Track method can be used where speed of analysis is a critical component; for example, when molten metal is being sampled and results are required in the shortest possible time. This method will produce suitable results for most samples; approximate cycle time is 2.25 minutes. As noted above, sampling and sample preparation are key elements to accurate O, N, and Hdetermination as well. It is up to the user to determine which method best meets their needs.
