| Abstract | ||||
| The effect of gamma irradiation on the thermal, mechanical parameters and electrical properties of Pb-5wt.% Sn-0.5 wt.% Zn alloy rapidly solidified from the melt was investigated. The results showed irregular behaviour of the parameters measured for samples irradiated with doses up to 200 KGy. Above 200 KGy a clear trend of variation tooks place. The values of the specific heat under constant pressure CP and the activation energy of ordering, U, showed opposite behaviours above 200KGy, up to 1 MGy. The deterioration of the elastic modulus and internal friction properties caused by irradiation appear to have a bad potential for using the present alloy as structural material soldering alloy in nuclear structures. The increased resistivity with irradiation was rendered to the increased scattering of transport electrons caused by the created scattering centres induced by gamma-rays. | ||||
