Redistribution of concentration of components during interdiffusion in Cu-Fe-Ni system

Autor: AA Alexander Kodentsov, Yu. E. Ugaste, F. Van Loo

Publikováno v: The Physics of Metals and Metallography, 113(12), 1182-1192. Maik Nauka-Interperiodica Publishing

Interdiffusion in a Cu-Ni-Fe system was studied at a temperature of 1000°C for three different diffusion couples. It has been shown that, in the studied diffusion couples, the distributions of some components of the system have a distinctly nonmonot

Investigation of interdiffusion and Kirkendall effect in the Co-Ni-Fe system: III. Dependence of diffusion parameters on the initial conditions

Autor: J. Priimets, Yu. E. Ugaste, AA Alexander Kodentsov

Publikováno v: The Physics of Metals and Metallography, 110(5), 485-491. Maik Nauka-Interperiodica Publishing

Dependences of the parameters of interdiffusion (effective coefficients, diffusion paths, Kirkendall shift) on the variation of the initial compositions of a diffusion couple have been studied on the concrete example of the Co-Fe-Ni system. The exper

Calculation of D in the case of diffusion from the vapor phase

Autor: A. Ya. Shinyaev, Yu. E. Ugaste

Publikováno v: Journal of Engineering Physics. 15:613-615

A method is proposed for determining the diffusion coefficient in cases when data on the surface concentration of the diffusing substance are lacking.
