Original abstract

This contribution contains the results of measurement of carbon redistribution in the welded joint of steels (low-alloy Si steel/low-alloy CrNiMoV steell and low-alloy Si steel/austenitic Cr18Ni9 steel). The measurement was carried out in the range of temperatures 500 – 1000 oC. On the basis of the measured concentration data the carbon diffusion coefficients were calculated and also their temperature dependences were determined.

Czech abstract

V příspěvku jsou předloženy výsledky měření redistribuce uhlíku ve svarovém spoji ocelí, který je tvořen nízkolegovanou CrNiMoV ocelí (ocel podle GOST 15Ch2NMFAA, označená pracovně P2) a nízkolegovanou křemíkovou ocelí (ocel typu 80C2,34Si, jejíž složení není stanoveno normou a je pracovně označena V). Měření bylo prováděno v rozmezí teplot 500 – 1000stC. Na základě změřených koncentračních údajů byly vypočteny difúzní koeficienty uhlíku a byly stanoveny jejich teplotní závislosti.
