An investigation of interdiffusion in a two-component mixture of powders of different degrees of dispersion

Conclusions The method in [1] was modified so as to permit calculation of concentration distributions for mixtures of powders of different dispersity.A comparative study of a number of histograms obtained experimentally [3] and calculated for the same conditions theoretically enables one to assume the presence of higher diffusion mobilities of atoms in the investigated objects than the values given in tables in [4], and indicates formation of conglomerates of nickel particles.It is also to be assumed that at annealing temperatures of over 700° ordering takes place, leading to retardation of homogenization in the case of real objects compared with homogenization when the Cu-Ni alloy is an ideal solution.
