The effect of high-pressure torsion on irradiation hardening of Eurofer-97

We investigate the effect of nano-structuring by high-pressure torsion (HPT) on the irradiation performance of Eurofer-97. Material was deformed to shear strains from 0 to ∼230, and then exposed to Fe3+ irradiation doses of 0.01 and 0.1 displacements-per-atom (dpa). Nanoindentation hardness increases monotonically with deformation, and with irradiation for the undeformed material. For both damage levels, less irradiation hardening is observed in severely deformed material. This effect is most prominent in the strain range ∼60 to ∼160, suggesting that nano-structuring may provide an approach for reducing irradiation hardening

Research data - the effect of high-pressure torsion on irradiation hardening of Eurofer-97

It contains the raw and processed data collected as a part of the study which resulted in the manuscript 'The Effect of high-pressure torsion on irradiation hardening of Eurofer-97'. The data was collected and processed at the University of Oxford. Matlab is required to view most of the data. Some files are in Microsoft Excel format and Igor format. Data processing and plotting scripts are all included. The scripts are all written in Matlab

The effect of high-pressure torsion on irradiation hardening of Eurofer-97

We investigate the effect of nano-structuring by high-pressure torsion (HPT) on the irradiation performance of Eurofer-97.
