Notes:
Quasi-nano filamentary copper-silver composites were irradiated and annealed to studyirradiation degradation behavior. The specimen was irradiated in CT hole of HANARO of KAERIfor 36 days at 320°C with the maximum neutron flux of 4.8x1020 n/cm2 (E〉1.0 MeV). The gammaheating rate was in the range of 2.0-6.45 W/gm. Irradiation embrittlement was observed. Hardnessdetermined by nano-indentation technique were 32.3 GPA for as-received condition, however, itdecreased 24.6 GPa due to gamma heating, which was above the value of the specimen with sameannealing effect without irradiation. Weight change of specimen with oxidation increased withannealing time, temperature and amount of dose 0.21-0.27 mR/h. Hardness change of the irradiatedspecimen followed by annealing was significantly dependent upon amount of dose of the specimen
