Abstract:

An investigation was made to determine the effect of the composition of heat-resistant alloys on diffusion mobility, the influence of refractory elements on the rate of the self diffusion processes, the influence of the structural condition of the alloy on the diffusion rate, and to obtain information on the mechanism of the diffusion process. A review of the literature is presented. Data are given on the influence of C, Al and Ti, W and Mo, and Al and Mo on the diffusion rate of Cr in Ni-base heat-resistant alloys. The results are discussed of a study of the effects of W, Mo, Nb, Ti, and V on the self diffusion of Fe in Fe-Ni alloy. Experiments are described on the effect of the structure of Ni-W alloy on the diffusion rate. Experimental data are discussed in relation to the diffusion mechanism and general conclusions are presented.
