HYDROGEN EMBRITTLEMENT OF Ni3Al+B
Scripta Metallurgica, 1985An 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
2016This 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.

Hydrogen Embrittlement and Hydrogen Absorption
2017The focus in this chapter is on the delayed failure, hydrogen embrittlement of steels, and detection of hydrogen in the metal. Several techniques for the detection of hydrogen in the metal are also explained. The diffusible hydrogen in the metal plays an important role in the delayed failure or hydrogen embrittlement, and the electrochemical detection ...

Hydrogen embrittlement of molybdenum
Scripta Metallurgica, 1975Results of tension tests at 279$sup 0$K on fine-grained polycrystalline Mo sheet specimens are reported. It was found that under conditions of simultaneous tension testing and cathodic charging, the hydrogen is present at high fugacity at the tip of a crack or other stress concentrations.

Hydrogen embrittlement of metals
Physica B: Condensed Matter, 2000Abstract Aluminium single crystals oriented for single slip have been studied by transverse-field muon-spin relaxation measurements after deformation in compression tests and after thermal annealing. The results show that positive muons can be used to investigate the interaction of hydrogen with dislocations in metals, which plays an important role ...

Hydrogen Embrittlement and Hydrogen-Dislocation Interactions
Corrosion, 1978This paper presents an analog of the Gibbs Adsorption equation which can be used to describe the effect of dissolved hydrogen on the energy of a dislocation. The magnitude of the effect is such that this equation helps explain hydrogen's influence on the fracture toughness of high strength steel.
