Characterization of Centreline Segregation of Continuously Cast Microalloyed Pipeline Steel
DownloadSpring 2017
Quantitative electron microprobe analysis (EMPA) was used in this study to quantify the segregation of alloying elements (e.g., Mn, Si, etc.) at the centreline for continuous cast slabs and pipes of microalloyed steel exhibiting different Mannesmann Ratings. Elemental segregation levels at the...
