Kennedy, J.R., Wiskel, J.B., Ivey, D.G., Henein, H.
The potential exists to use ultrasonic shear velocity for real time microstructure assessment of the quenching step in the teat treatment of L80 steel pipe. L80 steel samples were austenitized and subsequently cooled in different quench mediums (water, oil, heated oil, air and furnace) to produce...

Wiskel, J.B., Ma, J., Valloton, J., Ivey, D.G., Henein, H.
Strain aging of microalloyed steel pipe can occur at the relatively low temperatures associated with the pipe coating process and/or during long term storage. A Box-Behnken statistical design is used to determine the significant strain aging variables that affect the longitudinal yield strength...

Chatelier, C., Wiskel, J.B., Ivey, D.G., Henein, H.
Precipitates in thin-walled (11 mm) and thick-walled X70 (17 mm) microalloyed X70 pipe steel are characterized using Rietveld refinement (a.k.a. quantitative X-ray diffraction (QXRD)), inductively coupled plasma mass spectrometry (ICP), and energy-dispersive X-ray spectroscopy (EDX) analyses....

Gawor, S., Wiskel, J.B., Ivey, D.G., Liu, J., Henein, H.
A standard NACE hydrogen induced crack test was used to evaluate the resistance of two compositions of X70 steel (X70-X (Ca/S ratio of 2.5) and X70-B (Ca/S ratio of <0.5)) under severe (pH = 2.7 and 100% H2S) and mild (pH = 5.5 and 100% H2S) sour service conditions. An ultrasonic technique was...

Transverse Strain Aging Behaviour of Uncoated Thick Walled X70 UOE Microalloyed Steel Pipes
Download2018-01-01
Wiskel, J.B., Ma, J., Ivey, D.G., Henein, H.
Transverse tensile samples were extracted from the centreline position of three different compositions of uncoated thick walled microalloyed X70 UOE pipe at a location 180° from the weld. Aging heat treatments of 5, 15, and 25 minutes and temperatures of 175, 215, and 255°C were applied. Tensile...

Khodaie, N., Ivey, D.G., Henein, H.
Dilatometry is the most accurate and common method for measuring the kinetics of phase transformations in solid specimens. Despite the development of a more accurate technique, an inferior method, i.e., the lever rule, is widely used in the scientific community to interpret raw dilatometry data....
