Modeling of irradiation hardening of polycrystalline materials

Computational Materials Science, 2011
High energy particle irradiation of structural polycrystalline materials usually produces irradiation hardening and embrittlement. The development of predictive capability for the influence of irradiation on mechanical behavior is very important in materials design for next-generation reactors.

Hardening of copper irradiated at −195°C

Acta Metallurgica, 1961
Copper single crystals harden during neutron irradiation at −195°C and it is known that some recovery of this hardening (~ 10 per cent) occurs on annealing in the temperature range 0°–20°C, suggesting that the defects which become mobile at this temperature annihilate part of the damage responsible for the hardening.

Ion-irradiation-induced hardening in Inconel 718

Journal of Nuclear Materials, 2001
Abstract Inconel 718 is a material under consideration for areas in the target region of the spallation neutron source (SNS), now under construction at Oak Ridge National Laboratory (ORNL) in the US. In these positions, displacement damage from protons and neutrons will affect the mechanical properties.

Ion-irradiation hardening accompanied by irradiation-induced dissolution of oxides in FeCr(Y, Ti)-ODS ferritic steel

Journal of Nuclear Materials, 2018
Irradiation effects on hardness and phase stability were investigated for an FeCr(Y, Ti)-ODS ferritic steel strengthened by Y-Ti-O nano-particles after irradiation with 6.4 MeV Fe3+ at room temperature (RT) up to nominal damages of 2, 10 and 50 dpa. With

Helium irradiation induced hardening in MNHS steels

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2017
Abstract A recently developed reduced activation martensitic MNHS steel was irradiated with 200 keV helium (He) ions to a fluence of 1.0 × 10 20  ions/m 2 at 300 °C and 1.0 × 10 21  ions/m 2 at 300 °C and 450 °C. After irradiation, transmission electron microscopy (TEM) and nano-indentation measurements were used to investigate the hardness change ...

Hardening of Lithium Fluoride Crystals by Irradiation

Journal of Applied Physics, 1961
The very soft, pure crystals of LiF that are now commercially available are unsuitable for some experimental work because they suffer accidental plastic deformation during cleavage and tend to split on (110) planes. Irradiation with gamma rays produces harder crystals that can be cleaved and handled without much damage.

Ion irradiation hardening of C60 thin films

Thin Solid Films, 1999
Abstract The nanoindentation technique is used to measure the hardness and the Young’s modulus of ion irradiated C60 films, 70 nm thick, deposited on a Silicon substrate. An increase of hardness from 1.3 GPa for the pristine sample to 10 GPa after irradiation with 800 keV Bi+ and N2+ ions was observed.

Post-yield strain hardening behavior as a clue to understanding irradiation hardening

Journal of Nuclear Materials, 1998
We analyze the post-yield true-stress vs. true-strain flow behavior of neutron and electron irradiated reactor pressure vessel steels, A212B and A350, and binary alloys, Fe-0.28 Cu and Fe-0.74 Ni. The flow curves suggest that neutron-irradiation hardening has the same effect as strain hardening for all the materials examined. The post-yield flow curves,
