摘要：
The diffusion of hydrogen in FeTiHx (0.65<or=x<or=1.03) was studied as a function of temperature in the range 633<or=T<or=759K by means of quasielastic neutron scattering. The diffusion constant was found to obey an Arrhenius law D=D0 exp-EA/kT with D 0=(7.2+or-3.6)*10-4 cm2 s-1 and EA=500+or-50 meV. The results are discussed together with recent NMR studies of hydrogen diffusion in FeTiHx.
