This paper presents studies on the absorption and desorption behaviour of deuterium in Pd and Ti subjected to high pressure D2 ((6÷90) atm), by measuring the resistivity in cyclic conditions of temperature ranging from 77 K up to room temperature. Numerical calculations have also been performed for the deuterium absorption behaviour based on the diffusion equation. The results show that:a) deuterium starts to be absorbed into the bulk of Pd metal within (240÷270) K depending on the pressure;b) the absorption is dominated by a surface process.
