Application of color etching technique for observation of microstructure of Ni-base superalloys
Konečná, R. ; Kunz, Ludvík ; Skočovský, P. ; Lukáš, Petr ; Hrbáček, K.
Color etching technique was shown to yield valuable information about the gamma/gamma prime microstructure of Ni-base superalloys, changes of microstructure during material exploitation and about small defects in the form of cavities and pores.
THE INFLUENCE OF HIGH TEMPERATURES ON THE DIRECTION OF CARBON DIFFUSION FLUX IN STEEL WELDMENTS
Kučera, Jaroslav ; Michalička, Petr ; Million, Bořivoj ; Rek, A. ; Stránský, K.
The redistribution of carbon in steel weldments heated at temperatures situated in the range 500 °C up to 1100 °C is reported. The sandwich-like specimens used for experiments were made from the steels A .IDENT. (ČSN 17242) and K .IDENT. (P91). It was stated that at low temperatures (500-750 °C) the carbon diffusion flux is directed from the steel A into the steel K and at high temperatures from K into A.
Simultaneous diffusion of aluminium, carbon, chromium, iron and nickel in steel weldments at temperature interval 500 to 1100°C
Stránský, K. ; Million, Bořivoj ; Foret, R. ; Rek, A. ; Michalička, Petr
In this paper results of measurements of simultaneous diffusion of aluminium, carbon, chromium, iron and nickel in welded joints of unalloyed 12050+Al steel and high alloy austenitic chromium-nickel steel are presented.
On the redistribution of aluminium and carbon in a weld joints of steels in the temperature range 500-1100°C
Stránský, K. ; Million, Bořivoj ; Foret, R. ; Michalička, Petr ; Rek, A.
In this paper an original results of aluminium, chromium, iron,nickel and carbon redistribution in welded joints of unalloyed 12050+Al steel and high alloy austenitic chromium-nickel steel are presented.
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.
