Indentation testing on 3 MeV proton irradiated tungsten

Nuclear Materials and Energy, 2020
Tungsten samples have been irradiated with 3 MeV protons with dose rates of 1×10-04 to 5×10-05 dpa/s to doses of 0.01–0.67 dpa at 360 K in a pilot experiment. Micro- and macro-indentation were used to measure irradiation hardening in the samples.

The Effect of Rhenium Content on Microstructural Changes and Irradiated Hardening in W-Re Alloy under High-Dose Ion Irradiation

Nanomaterials, 2023
An amount of 100 dpa Si2+ irradiation was used to study the effect of transmutation rhenium content on irradiated microscopic defects and hardening in W-xRe (x = 0, 1, 3, 5 and 10 wt.%) alloys at 550 °C.

Atomistic analysis of the mechanisms underlying irradiation-hardening in Fe–Ni–Cr alloys

International journal of plasticity
This work presents a comprehensive examination of the physical mechanisms driving hardening in irradiated face-centered cubic FeNiCr alloys. The evolution of irradiation-induced defects during shear deformation is modeled by atomistic simulations through

Post-irradiation annealing behavior of irradiation hardening of China low-Cu RPV steel

, 2020
In the present work, irradiation hardening of a low-copper reactor pressure vessel steel (Chinese A508-3) is studied. Specimens of the RPV steel were irradiated with high-energy Fe ions at a terminal of a cyclotron at a low temperature around 173 K to ...

Effect of Au-ions irradiation on microstructure and mechanical properties of FeCrAl coating

Journal of Materials Research and Technology, 2023
Six kinds of FeCrAl coatings with different Cr and Al contents were irradiated by 6 MeV Au-ions with a damage level of 20 dpa. The results showed that the surface roughness and grain size of the coatings increased significantly after irradiation ...
