Oxygen, Nitrogen, and Hydrogen in Refractory Metals
Summary
One of the most critical chemical specifications of titanium alloys is the hydrogen content. Too high of a
hydrogen content can cause hydrides to precipitate, which can lead to embrittlement and subsequent
cracking when the alloy is stressed. Hydrogen pickup typically occurs during downstream processing steps
such as heat treating, pickling, and cleaning.
The LECO ONH836 is a simultaneous oxygen, nitrogen, and hydrogen determinator that utilizes an electrode furnace, inert carrier gas, and both infrared and thermal conductivity detection to meet the analytical needs of the refractory metal industry.
This application note was written specifically for use with the LECO ONH836 series determinator.
