摘要：

Samples of three copper alloys were irradiated in the BOR-60 fast reactor up to 1.6 x 10(22) n/cm2. Irradiation temperatures were 350-460-degrees-C. Mechanical properties and the structure of the irradiated materials were studied. The precipitation-hardened alloys exhibited a decrease of the yield strength with increasing irradiation temperature and dose. After irradiation to (1.5-1.6) x 10(22) n/cm2 at about 450-degrees-C large precipitates were observed in the alloys, which were accompanied by softening.
