Hydrogen effects in non-ferrous alloys: discussion

Abstract

This is a transcript of the discussion session on the effects of hydrogen in the non-ferrous alloys of zirconium and titanium, which are anisotropic hydride-forming metals. The four talks focus on the hydrogen embrittlement mechanisms that affect zirconium and titanium components, which are respectively used in the nuclear and aerospace industries. Two specific mechanisms are delayed hydride cracking and stress corrosion cracking.This article is part of the themed issue 'The challenges of hydrogen and metals'.

The challenges of hydrogen and metals

“…We owe a particular debt to the student and postdoctoral scribes who took copious notes during the sessions and later on transcribed from the audio recordings to produce manuscripts of the seven discussion papers which appear in this issue. The scribes are: Yi-Sheng Chen [9] (Department of Materials, University of Oxford); Felicity Dear [10] (Department of Materials, Imperial College London); Dr Henry Lambert [11] (Department of Physics, King's College London); Mitesh Patel [12] (Department of Physics, Imperial College London); E. Luke Simpson [13] (Department of Physics, King's College London); Guy Skinner [14] (Department of Physics, King's College London); and Miles Stopher [15] (Department of Materials, University of Cambridge).…”
