| Popis: | Copper-rich precipitates formed in iron based dilute alloys by irradiation or thermal ageing, have been investigated using small angle neutron scattering (SANS). In particular, FeCu1.5% has been studied after either 2.5 MeV electron irradiations at 300 o C or thermal ageing at 500 o C. Size distribution, composition and number density of the clusters were deduced from SANS data. In addition, microhardness measurements allowed to correlate precipitates configuration with alloys hardening. The precipitation mechanism looks the same for both kinds of ageing, but irradiation induces an additional contribution to hardening. A linear correlation between duration of thermal ageing and irradiation fluence can be established |
