A contribution to the redistribution of aluminium in a weld joints of steels
Stránský, K. ; Million, Bořivoj ; Foret, R. ; Michalička, Petr ; Rek, A.
An original results of redistribution in welded joints of unalloyed 12050+Al steel and high alloy austenitic chromium-nickel steel are presented. The diffusion coefficients of Al, Cr, Fe and Ni were established and the relation among diffusion coefficients was discussed.
On the thermodynamic and the diffusion interaction coefficients and their mutual relation
Řeháčková, L. ; Million, Bořivoj ; Dobrovská, J. ; Stránský, K.
This contribution deals with the mutual relation of the thermodynamic and diffusion interaction coefficients. The thermodynamic interaction coefficients were determined from the concentration discontinuity of carbon at the interface of the welded steels, the diffusion interaction coefficients from the concentration dependence of the diffusion characteristics.
Application of ab initio electronic structure calculations to grain boundary structure
Šob, Mojmír ; Turek, Ilja ; Wang, L. G. ; Vitek, V.
State-of-the-art electronic structure methods are briefly characterized and their application to electronic structure of certain grain boundaries in tungsten and iron as well as to magnetic behaviour of Ru and Rh overlayers on the Ag(001) substrate is shown.
