Classical molecular dynamics simulations were used to study the interdiffusion of liquid Na-K alloys, as a function of concentration, for compositions ranging from 10 to 90at%Na. The self- and interdiffusion coefficients were deduced. The results were compared with the predictions of Darken’s law, and the validity of the approximation was considered.
