SELF-DIFFUSION OF PALLADIUM IN SILVER-PALLADIUM ALLOYS

摘要

The self-diffusion coefficient of palladium is reported for 850P and 8966 in a series of silver-palladium solid solutions in rich the atom fraction of palladium ranges from 0 to 0.204. For each temperature the data may be represented by an equation of the Form Dad= DDexp(bX), where X is the atom fraction of palladium •and b = - 7.5. Alternatively, the results conform to the equationnDad = 0.0l66Cxp(-17.21 Tm/T), indicating that a correspondingnstates law is followed in this nearly ideal system.
