Název v původním jazyce

Tracer diffusion of 65Zn, 110mAg and 88Y in QE22 metal matrix composite

Popis výsledku v původním jazyce

Tracer diffusion of 65Zn, 110mAg and 88Y in QE22 metal matrix composite was measured by serial sectioning method in the temperature interval 646?728 K. 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.
