Multiscale modelling of diffusion and retention of hydrogen in multi-occupancy traps in irradiated bcc metals
Daniel Mason, Sanjeet Kaur, Samanyu Tirumala +3
We use molecular dynamics simulations to directly compute the effective diffusivity of hydrogen gas atoms in homogeneous distributions of monovacancies in tungsten and vanadium, an…
Thermodynamics and dynamics of non-compact prismatic dislocation loops simulated using a machine-learning model
Sho Hayakawa, Sergei L. Dudarev, Max Boleininger
We explore how the thermodynamic properties and dynamics of a self-interstitial prismatic dislocation loop are affected by microscopic-scale variations in its geometric configurati…
Atomistic simulations of athermal irradiation creep and swelling of copper and tungsten in the high dose limit
Luca Reali, Max Boleininger, Daniel R. Mason +1
Radiation creep and swelling are irreversible deformation phenomena occurring in materials irradiated even at low temperatures. On the microscopic scale, energetic particles initia…
Simulated TEM imaging of a heavily irradiated metal
D. R. Mason, M. Boleininger, J. Haley +4
We recast the Howie-Whelan equations for generating simulated transmission electron microscope (TEM) images, replacing the dependence on local atomic displacements with atomic posi…
Fast low-temperature irradiation creep driven by athermal defect dynamics
Alexander Feichtmayer, Max Boleininger, Johann Riesch +7
The occurrence of high stress concentrations in reactor components is a still intractable phenomenon encountered in fusion reactor design. We observe and quantitatively model a non…
Dislocation density transients and saturation in irradiated zirconium
Andrew R. Warwick, Rhys Thomas, Max Boleininger +10
Zirconium alloys are widely used as the fuel cladding material in pressurised water reactors, accumulating a significant population of defects and dislocations from exposure to neu…
Microstructure of a heavily irradiated metal exposed to a spectrum of atomic recoils
Max Boleininger, Daniel R. Mason, Andrea E. Sand +1
At temperatures below the onset of vacancy migration, metals exposed to energetic ions develop dynamically fluctuating steady-state microstructures. Statistical properties of these…
Intense γ-photon and high-energy electron production by neutron irradiation: effects of nuclear excitations on reactor materials
Luca Reali, Mark R. Gilbert, Max Boleininger +1
The effects of neutron irradiation on materials are often interpreted in terms of atomic recoils, initiated by neutron impacts and producing crystal lattice defects. In addition, t…
Volume of a dislocation network
Max Boleininger, Sergei L. Dudarev, Daniel R. Mason +1
We derive a simple analytical line integral expression for the relaxation volume tensor of an arbitrary interconnected dislocation network. This quantity determines the magnitude o…
Macroscopic elastic stress and strain produced by irradiation
Luca Reali, Max Boleininger, Mark R. Gilbert +1
Using the notion of eigenstrain produced by the defects formed in a material exposed to high energy neutron irradiation, we develop a method for computing macroscopic elastic stres…
Parameter-free quantitative simulation of high dose microstructure and hydrogen retention in ion-irradiated tungsten
Daniel R. Mason, Fredric Granberg, Max Boleininger +3
Hydrogen isotopes are retained in materials for fusion power applications, changing both hydrogen embrittlement and tritium inventory as the microstructure undergoes irradiation da…
Statistical mechanics of kinks on a gliding screw dislocation
M. Boleininger, M. Gallauer, S. L. Dudarev +3
The ability of a body-centered cubic metal to deform plastically is limited by the thermally activated glide motion of screw dislocations, which are line defects with a mobility ex…
