| Abstract |
The diffusivities of hydrogen in Zr-0.5, 1.05, 1.5 and 2.3 at.% Ni alloys were respectively measured over 900-1080℃ by the gravimetric technique. The diffusion activation energies for hydrogen increased linearly as Ni concentration increased and expressed by the equation. Q_D=(8297±221)+(3366±148)×(at.%Ni) ㎈/mole H₂ while the hydrogen diffusivities decreased, Ni concentration is increased, The diffusivity data at each alloy composition are presented. |
