    Diffusion of Carbon and Manganese in Fe-C-Mn

  • Original language description

    In this paper, the results of measurements of chemical diffusion of C in weldments of Fe- C-Mn alloys with content of 0-15 % Mn, are reported. Alloys were cast in induction furnace under protective Ar atmosphere. They were hot-forged to rods of diameter15 mm, machined down to diameter 12 mm, and cut into pieces of 4 mm thickness. These cylindrical samples were metallographically polished. Diffusion couples, welded by electrical impulse, were sealed together with Ti-chips, into evacuated silica ampoules. After that, they were annealed at 1073-1373 K for 96-1.5 hours, respectively. Measurement of C redistribution was done in a normal direction to welding interface using electron-scanning microscope Philips SEM-505WDS equipped with Microspec WDX-2A. Diffusion coefficients of C were obtained and the relations between manganese and carbon were found.

    Difúze uhlíku a manganu v Fe-C-Mn

  • Czech description

    V práci jsou uvedeny výsledky měření difúze uhlíku ve svarových spojích slitin Fe-C-Mn s obsahem 0-15hm.% Mn. Slitiny byly odlity v indukční peci pod ochrannou atmosférou Ar. Ingoty byly za tepla vykovány na tyčky o průměru 15mm, osoustruženy na průměr 12mm a rozřezány na vzorky o tloušťce 4mm. Tyto vzorky byly metalograficky vyleštěny. Difúzní páry byly svařeny elektrickým šokem a zataveny společně s Ti třískami do křemenných ampulí. Potom byly žíhány při teplotách 1073-1373K po dobu 96-1,5h. Měření redistribuce uhlíku bylo provedeno ve směru kolmém na svarové rozhraní pomocí rastrovacího elektronového mikroskopu Philips SEM-505WDS se zařízením Microspec WDX-2A. Byly získány difúzní koeficienty uhlíku a nalezen vzájemný vztah mezi uhlíkem a manganem.
