20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...
Residual stresses can have a significant impact on the stability of structural members. In the case of I-section beam elements, such stresses can impact lateral--torsional buckling (LTB) capacity, particularly in the inelastic range. I-sections are typically fabricated by either rolling as a...
It has become common for steel fabricators to find torsional loads included in the design documents of many industrial steel structures. These loads arise in wide-flange beam-to-column moment connections when the beam is subject to weak axis bending, which in turn, is transferred to the column as...

Oil and gas are known for their huge-size and complex projects that consist of multiple trades’ subprojects such as concrete, steel, and piping. These subprojects are executed within a confined area during a limited time frame. This requires careful planning and coordination between these...
Coped beams are susceptible to fatigue cracking in the web at the cope radius when subjected to tension in the coped region. Use of an adhesively bonded composite patch over the crack can reduce the stress concentration and delay further crack growth. This report contains the results of a...
Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....
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...
The formation of bainite is the most studied and the most debated phase transformation in steels, with research spanning almost a century. With two theories of transformation, the transformation mechanism of bainite is still a disputed subject among physical metallurgists. Upper bainite and lower...
This thesis presents work performed to model and measure the effect of run-out table cooling on a thick walled X70 steel. During run-out table cooling, the steel undergoes several phase transformations that will affect its microstructure, and thus, its mechanical properties. To predict the steel...
