In metals, embrittlement is a loss of ductility, which results in metal becoming brittle. Ductility is simply the ability of any material to have its shape changed. At Cadorath, the focus is on removing or minimizing hydrogen embrittlement. In particular, hydrogen gas can be absorbed by certain metals, potentially resulting in the cracking of welds and creation of other stress-induced cracks. These fractures can be prevented by using component-specific temperatures with the right equipment—causing the hydrogen to diffuse out of the metal.
ADVANTAGES OF EMBRITTLEMENT RELIEF
- Embrittlement appears to occur particularly in titanium, aluminum alloys and high-strength steels.
- Embrittlement relief is often used in the aerospace industry to remove hydrogen from airplane fasteners and other metal parts.
ORIGINS AND DEVELOPMENT
A common method for reducing embrittlement is to perform a hydrogen bake-out cycle in special ovens. To be effective, bake-out must be done within a few hours after the introduction of hydrogen into the material.
Embrittlement can be a serious issue, particularly when applied to large public projects, such as bridges—just one of the many reasons embrittlement relief processes are so critical.
