Hydrogen embrittlement

Proceedings, annual meeting, Electron Microscopy Society of America, 1989
The effects of hydrogen on the fracture of metals will be reviewed using a selection of observations based on the use of in situ environmental cell experiments. These were developed to allow understanding of the mechanisms of the failure process. The in situ technique, combined with use of the environmental cell, is well suited to mechanistic studies ...

HYDROGEN EMBRITTLEMENT OF Ni3Al+B

Scripta Metallurgica, 1985
An experimental study is conducted to verify the hypothesis that Ni3Al, which exhibits an L1(2) structure and remains ordered up to the melting point, would be severely embrittled by hydrogen and that this effect would be reversible. Unlike its effect on Ni, boron alloying is found not to suppress hydrogen embrittlement in NiAl + B.

Hydrogen Embrittlement: Mechanisms

2016
This entry reviews hydrogen embrittlement mechanisms that have been proposed from the 1940s to date to explain the hydrogen-induced degradation phenomena occurring mainly in iron, steel, and their alloys. Hydrogen embrittlement mechanisms can be categorized into three types: brittle fracture, phase transformation, and ductile fracture.
