CHARACTERIZATION OF PRECIPITATES IN SEGREGATED REGIONS OF A Nb BEARING API-X70 MICROALLOYED STEEL

Despite technological advances in steelmaking equipment and processes, the formation of precipitates with sizes higher than 1 mu m is still observed in some cases of microalloyed steel plates. Even with the current controls, process variations can lead to formation of precipitates harmful to the mat...
