Effects of complex alloying on diffusion processes in the Ni-Ti. Ni-Ti- Cr, Ni-Ti-Cr-W-Al. Ni-Ti-CrW-Al-B. Ni-Ti-Cr-W-Al-Mo-C. and Ni-Ti-CrW-Al-Mo-C - Nb systems were studied at temperstures of 950 to 1250. Iron with the radioactive isotope Fe/sup 59/ was used as diffusing element. Results revealed that in 7- and 8-component nickel alloys the diffusion activity is more than doubled in comparison to pure nickel. Results agree with published data on the effects of chemical complexes on the activation energy of diffusion and coincide with the data on alloy stability in transitions from two component alloy to ternary and more complex ones. At 1100- the 8-component alloy reaches the maximum endurance point. The examined data indicate that diffusion and stability are determined, basically, by the same factors. (R.V.J.)
