Abstract
To date, information on interdiffusion in intralanthanide systems is limited. Interdiffusion studies have been reported for the Pr-Nd, La-Pr, and La-Ce systems. Yet, no data is available for the Ce-Nd system. This paper reports the results of Ce-Nd diffusion couples annealed at 425 C, 550 C, and 650 C. Both intrinsic and interdiffusion data have been calculated, as well as activation energy information as a function of composition. Comments will be made on how well the composition of the boundaries of the [({gamma}Ce) + ({beta}Ce, {alpha}Nd)] two-phase region in the Ce-Nd phase diagram agree with diffusion couple results.
