Description
| - This paper addresses the issue of C and N redistribution in weld joints of creep-resistant chromium steels. The redistribution of C and N was measured using the wave-dispersive X-ray method. The conditions of the long-term diffusion annealing process were: temperature 575, 625 and 700 oC; time 10, 100, 1 000 and 5 000 hours. It was ascertained that C and N diffused from the low-alloy steels to the high-alloy steel P91. The carbon diffusion coefficients in the individual steels of 15128/P91 and SK3STC/P991 weld joints, the ratio between the thermodynamic activity coefficients of carbon in joints, the diffusion interaction parameters , and their temperature dependencies were estimated from carbon concentration curves. The paper also contains a microstructure analysis of decarburized and carburized zones in the weld joints studied.
