Abstract:

By the method of helium thermal desorption from submicrocrystalline palladium presaturated in the gaseous phase, the diffusion coefficient D-eff and solubility coefficient C-eff of helium are measured in the range P=0-3 MPa and T=293-508 K. The pressure dependence of C-eff flattens at high pressures. At low saturation pressures, the temperature dependences of the diffusion and solubility coefficients may be divided into (1) high-temperature (400-508 K) and (2) low-temperature (293-400 K) ranges described by the exponentials D-1,D- 2=D-0 exp (-E-1, 2(D)/kT ) and C-1,C- 2=C-0 exp (-E-1, 2(S)/kT ). The energies of diffusion activation are E-2(D)=0.0036+/-0.0015 eV and E-1(D)=0.33+/-0.03 eV, and the solution energies are E-2(S)=-0.025+/-0.008 eV and E-1(S)=0.086+/-0.008 eV in the low- and high-temperature ranges, respectively. Mechanisms behind the diffusion and solution of helium are discussed. (C) 2002 MAIK ``Nauka/Interperiodica{''}.
