Stránský, K. ; Million, Bořivoj ; Michalička, Petr ; Foret, R. ; Rek, A.
Measurements of Al, Cr, Fe, Ni and C diffusion in steel welded joints of the modified 12050 steels and high alloy austenitic chromium-nickel steel 17242. Three types of aluminium modified steels were used: 0.34, 0.49 and 1.15 wt.%Al. The isothermal annealing 500-1100°C (with the steps 50°C) and 1050-1.5 hours of weld joints was applied. The diffusion coefficients Al, Cr, Fe, Ni and C were established and the relations among diffusion coefficients were discussed.
