In the case of the reinforced alloy, the effective diffusion coefficients Deff were obtained and interface diffusion coefficients D i in the interface boundaries were estimated. Both temperature dependences of Deff and D i were not Arrhenius-type. This feature was explained by the large difference in coefficients of the thermal expansion of the metal matrix and the reinforcement. In the case of 88Y diffusion in un-reinforced QE22 alloy, it was found that yttrium diffuses along dislocations that act as paths of rapid diffusion. Diffusivity of 88Y along dislocations, a2sDd, was estimated. Pracoviště Ústav fyziky materiálu Kontakt Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Rok sběru 2009
