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.
Carbon and phosphorus redistribution in welded joints of carbon steels CSN(412050+0.1
Million, Bořivoj ; Stránský, K. ; Michalička, Petr ; Foret, R. ; Rek, A.
The diffusion specimens were isothermally annealed in the temperature range of 500 to 1100řC intervals. The concentration of P, C, Cr and Ni were measured by applying X-ray energy dispersion anlysis. The diffusion coefficients of P, C, Cr and Ni and thermodynamic interaction parameters were calculated. The uphill diffusion of phosphorus was observed on welding interface.
