摘要：

The terminal solid solubility of interstitial carbon in palladium has been determined after equilibrating pure palladium with graphite in the temperature range from 1083 to 1473 K. The solubility is of the same order of magnitude as those in nickel and cobalt and is in agreement with one of the two reports in the literature. The diffusion coefficient has been measured by diffusion couple experiments at high temperatures (1223 to 1378 K) and by anelastic relaxation experiments at low temperatures (430-460 K). The results obtained for the two temperature regions are in reasonable accord with each other. The diffusion of carbon in palladium is faster than in nickel, in cobalt and in gamma iron.
