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.

736 Series: Oxygen/Nitrogen by Inert Gas Fusion

The 736 family of Elemental Analyzers is designed for routine measurement of oxygen and nitrogen content of

inorganic materials, ferrous and nonferrous alloys, andrefractory materials using the inert gas fusion technique.

These instruments feature our Cornerstone brand ® software, a custom interface designed specifically for

touch-screen operation. Developed by combining longterm research with customer feedback, this easy-to-use

software gives you complete access to instrument control, analysis settings, diagnostics, reporting, and more—without sacrificing valuable bench space.

Sample Preparation

Sampling and sample preparation of refractory metals such as titanium and zirconium is somewhat different from that of steel. Unlike steel samples, hydrogen is not as mobile in this group of materials; therefore, storage in liquid nitrogen or dry ice is not required. However, it is important to keep the sample cool when cutting or sectioning. Sample preparation for oxygen and nitrogen determination has beendifferent from that of hydrogen determination.
