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...

This thesis presents work performed to improve the work hardening behaviour of an X80 microalloyed steel through various Interrupted Thermal Treatments (ITT). The aim of this work was to determine the relationships between thermal history, microstructure and mechanical properties through both...

X-ray diffraction (XRD) profile fitting (Rietveld method) was used in this study to characterize the microstructure for seven microalloyed steels, which were produced through thermomechanical controlled processing (TMCP). Microstructure characterization was conducted through the strip thickness....

Traditionally in pipeline steels and welds, ultrasonic testing (UT) has been used for crack and/or flaw detection. The work presented in this Thesis explores the use of this technique to characterize the microstructure of pipe steels. Ultrasonic velocity calculations, for shear and longitudinal...
