International audience; When B4C boron carbide is irradiated in neutron reactors, high quantities of helium are produced due to the 10B(n,α)7Li neutron absorption reactions. It is well known that most helium remains in the material, this inducing sw

Evolution of defects in titanium grade 2 under Ti2+ion irradiation

Autor: M. Le Thuaut, J. Malaplate, T. Millot, Moukrane Dehmas, E. Jouanny, S. Doriot, Lucien Allais

Publikováno v: Journal of Microscopy. 265:275-286

The complexity and diversity of microstructure involved in titanium alloys make it rather difficult to quantitatively describe defect evolution due to irradiation. This paper focuses on defect evolutions of commercially pure titanium grade 2 under Ti

International audience; Under neutron irradiation, radiation enhanced beta-Nb nano-precipitates develop within the α-grains of the Zr-Nb alloys. This radiation enhanced precipitation is of great interest since it may have some influence on the post-

Publikováno v: Journal of Nuclear Materials. 437:365-372

To further advance understanding of microstructural evolution in zirconium alloys for high burnup applications in PWR, it is important to obtain precise characterizations of second-phase particles present in the bulk alloys as a function of the neutr
