Influence of the thermomechanical process on the behavior of 6xxx aluminum alloys under ion irradiation

Abstract : Aluminum alloys have been widely used in nuclear research reactors (NRRs) since the 1960s. This choice is mainly due to the very high neutron transparency of such alloys coupled with the low temperature of NRRs. In pressurized NRR, thicker sections are designed to achieve higher mechanical strengths, but issues arise on the irradiation damages in the thickness. Several microstructures of a typical aluminum alloy from the 6xxx series where achieved and samples with the obtained different microstructures were irradiated with different ion fluxes in order to reproduce the irradiation behavior that can be observed in reactor. The results obtained here are compared to literature results from neutron-irradiated samples and modelled in order to predict swelling behavior under irradiation.
