The goal of this work is to make a contribution to the understanding of the microscopic mechanisms of H-induced intergranular damage. We develop an embedded-atom method interatomic potential for H in the Al–Mg system with the main aim of reproducin

By neutron spectroscopy, we studied vibrations of H interstitials in two austenitic fcc steels (Fe0.55Cr0.20Mn0.10Ni0.15 and Fe0.54Cr0.27Ni0.19) doped with 0.37 and 0.33 at% H. The band modes, in which H vibrates with its metal neighbours, cause a we

The interest in ultra-high-purity (UHP) metals and alloys (including single crystals and bicrystals) in studying damage mechanisms is presented through three practical cases of environment or precipitation-induced damages in nuclear power plants. Fir

The cyclic plasticity mechanisms in body-centred cubic (bcc) materials are strongly temperature and strain-rate dependent. At low temperatures, slip asymmetry (due to low mobility of screw dislocations) occurs and leads to changes of the grain shape,

The mechanical behaviour of nickel base superalloy 718 was investigated by means of constant extension rate tensile (CERT) tests performed at 5×10 −7 s −1 , in air and under secondary vacuum, in the temperature range 400–600°C. Below 470°C,
