Neutron-induced dpa, transmutations, gas production, and helium embrittlement of fusion materials
M. R. Gilbert, S. L. Dudarev, D. Nguyen-Manh +3
In a fusion reactor materials will be subjected to significant fluxes of high-energy neutrons. As well as causing radiation damage, the neutrons also initiate nuclear reactions lea…
A novel Monte Carlo model and simulations of magnetic alloys for nuclear applications
M. Yu. Lavrentiev, D. Nguyen-Manh, J. Wrobel +1
We develop a Magnetic Cluster Expansion (MCE) model for binary bcc and fcc Fe-Cr alloys, as well as for fcc Fe-Ni alloys, and apply it to the investigation of magnetic properties o…
Constrained non-collinear magnetism in disordered Fe and Fe-Cr alloys
D. Nguyen-Manh, Pui-Wai Ma, M. Yu. Lavrentiev +1
The development of quantitative models for radiation damage effects in iron, iron alloys and steels, particularly for the high temperature properties of the alloys, requires unders…
Degenerate transition pathways for screw dislocations: implications for migration
Mark R. Gilbert, Sergei L. Dudarev, Peter M. Derlet
In body-centred-cubic (bcc) metals migrating 1/2<111> screw dislocations experience a periodic energy landscape with a triangular symmetry. Atomistic simulations, such as those per…
High energy collision cascades in tungsten: dislocation loops structure and clustering scaling laws
A. E. Sand, S. L. Dudarev, K. Nordlund
Recent experiments on in-situ high-energy self-ion irradiation of tungsten (W) show the occurrence of unusual cascade damage effects resulting from single ion impacts, shedding lig…
