Procedure – Powder/Chip Samples

Determine the instrument blank.

Press the Analyze button on the instrument screen again, the loading head slide-block will close and the lower electrode will open.

Clean the upper and lower electrode either manually or remove the crucible and press the analyze button to clean with an automatic cleaner if applicable.

Add approximately 0.05 g of *** Graphite Powder to a 782-720 Graphite Crucible.

Firmly place the crucible on the lower electrode tip or appropriate autoloader position.

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.

Sample Preparation

Sampling and sample preparation is an important issue because traditional methods used to obtain samples for oxygen and nitrogen determination are different from those recommended for hydrogen, especially when sampling molten metal. The main difference in steel sampling procedures for oxygen/nitrogen and hydrogen is due to the mobilityof hydrogen. Special precautions must be used when sampling for hydrogen. From molten steel and iron, a sample must be quickly quenched in cold water and chilled in a refrigerant such as liquefied nitrogen or a mixture of acetone and solid carbon dioxide in order to reduce losses of hydrogen from diffusion. Losses of oxygen and nitrogen from diffusion are not a problem. A sample that is taken for hydrogen and

chilled in a refrigerant can also be used for oxygen and nitrogen determination. However, a sample that is typically taken for oxygen and/or nitrogen determination is not suitable for hydrogen determination due to hydrogen loss (diffusion). Surface contamination must be removed by filing or light grinding, using care not to overheat the sample.
