Abstract
In the present paper 1 the Hall method HM specifically designed for determining the interdiffusion coefficient at the low and high composition limits of the corresponding interdiffusion composition profile is further developed in order to be applied to the whole composition profile resulting in the Extended Hall method EHM 2 A comparative study of the HM EHM BoltzmannMatano BM and Sauer and Freise SF methods is performed using composition profiles generated by computer simulation The results clearly indicate that the HM/EHM technique is only applicable when the interdiffusion coefficient is constant ie independent of composition or almost constant at the low composition regions In all other cases the BM and SF methods give the best agreement with the input interdiffusion function even at the ends of the composition profiles
