Atom Probe Tomography Study of Hydrogen Embrittlement in X65 Pipeline Steel

Scientific publishing and peer-reviewed research dissemination

A cutting-edge analytical technique that allows researchers to observe and quantify hydrogen and its isotope deuterium at the atomic scale within materials, providing detailed maps of where hydrogen atoms settle within steel.

The use of deuterium, a stable heavier isotope of hydrogen, as a proxy to distinguish between hydrogen introduced during specimen preparation and hydrogen naturally present in the material.

Material engineering approaches to prevent hydrogen-induced weakening of steel through alloy design, surface treatments, and microstructural control.
