Hydrogen environment embrittlement of astroloy and Udimet 700 (nickel-base) and V-57 (iron-base) superalloys [PDF]

The sensitivity to hydrogen environment embrittlement of three superalloys was determined. Astroloy forgings were resistant to embrittlement during smooth tensile, notched tensile, and creep testing in 3.5-MN/sq m hydrogen over the range 23 to 760 C. The

Producing High Concentrations of Hydrogen in Palladium via Electrochemical Insertion from Aqueous and Solid Electrolytes

, 2018
Metal hydrides are critical materials in numerous technologies including hydrogen storage, gas separation, and electrocatalysis. Here, using Pd-H as a model metal hydride, we perform electrochemical insertion studies of hydrogen via liquid and solid ...

Hydrogen embrittlement and strain rate sensitivity of electrodeposited copper: part I – the effect of hydrogen content

npj Materials Degradation
Slow strain rate tensile testing was conducted on electrodeposited copper, which is a candidate coating material for used nuclear fuel containers. Embrittlement was observed in electrodeposited copper containing 26.4 ± 1.0 ppm hydrogen, with a strain ...

Hydrogen Embrittlement of Steel

Zairyo-to-Kankyo, 2011
鉄鋼材料の水素脆化全般をまとめ，その対策として，水素侵入抑制を鋼材側から検討した例を述べた．スケール直下のNi濃化層を活用することにより，水素侵入を抑制し，水素脆化を抑制できた．また，高合金化すると，素材としての水素脆化特性は良好となっても，ボルトなど実部品を用いた水素脆化特性は必ずしも良好とはならない．これは接触腐食による水素侵入が増大するためで，Ni多量添加によって抑制可能である．
