چکیده انگلیسی
U-10Zr/Zircaloy-4 (U-10Zr/Zr-4) diffusion couples were prepared by a coating and hot-rolling method and the compatibilities of the U-10Zr/Zr-4 diffusion couples were investigated by metallographic microscope (OM), scanning electron microscope (SEM) and energy-dispersive spectroscopy (EDS) analysis. The results show that the interface layer of the U-10Zr/Zr-4 couple grows uniformly, no cracks and pores at the interface observed. The compositions of the interface layer of the U-10Zr/Zr-4 couple vary parabolically. From U-10Zr side to Zr-4 side, the content of U gradually decreases, while the content of Zr increases. Moreover, the growth of the interface layer of the U-10Zr/Zr-4 couple follows the parabolic growth law. The diffusion coefficient constant is 2.70E-1 m2/s and the diffusion activation energy is 260.49 Ã 103 J/mol. The diffusion coefficients at 750 °C and 800 °C are 1.33E-14 m2/s and 5.54E-14 m2/s respectively.
