Abstract Recurrent Neural Network (RNN) based surrogate models constitute an emerging
class of reduced order models of history-dependent material behavior. Recently, the authors …

How displacement damage defects generate and evolve in materials irradiated by energetic
particles is a perennial topic in the field of nuclear materials. Here we experimentally reveal …

Plasticity of irradiated UO 2 is of major interest to improve the risk assessment of the nuclear
fuel cladding failure in the case of design basis accidents. In this study, we investigate the …

In fusion reactor environment, helium bubble acts as a crucial inducement to the
performance degradation of plasma facing tungsten, leading to irradiation hardening and …

High entropy alloys (HEAs) exhibit outstanding radiation resistance over traditional alloys
owing to severe lattice distortion, and therefore, would be regarded as candidate materials …

Exposure of metals to neutron irradiation results in an increase in the yield strength and a
significant loss of ductility. Irradiation hardening is also closely related to the fracture …

A classical crystal plasticity formulation based on dislocation slip was extended to include
the mechanisms of dislocation channelling, with associated strain softening which is …

Tungsten is considered as the plasma-facing material in the nuclear fusion device, which
has to withstand coupled irradiation, mechanical and thermal conditions. To guarantee the …

This work presents a comprehensive examination of the physical mechanisms driving
hardening in irradiated face-centered cubic FeNiCr alloys. The evolution of irradiation …

High-resolution electron backscatter diffraction (HR-EBSD) can provide an estimate of
elastic strains at a microscopic scale. Due to the need for high-quality Kikuchi patterns, HR …
