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 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...

Welding is defined as the joining of metals with extreme heat, producing fumes, which consist of harmful metals and ultrafine particulates that may lead to detrimental health effects. Currently, air sampling is the primary method to determine welding fume exposure, but is not always feasible....

Microstructural Characterization of Chromium Carbide Overlays and a Study of Alternative Welding Processes for Industrial Wear Applications
DownloadSpring 2014
Microstructural features of chromium carbide overlays (CCOs) were examined in this work. It was found that the microstructures can contain unmelted alloy powders. It was also shown that the structures of the primary M7C3 carbides are long hexagonal rods. Change in the microstructure from the top...

Modeling of the Effect of Run-out Table Cooling on the Microstructure of a Thick Walled X70 Skelp
DownloadSpring 2018
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...

Optimization techniques, in conjunction with a finite element thermal model, are used in this thesis to optimize the temperature profile (i.e. cooling rate and coiling temperature) of a steel skelp during laminar cooling. Optimization parameters include skelp velocity, laminar cooling bank...

Newer energy codes for buildings in Canada now require energy losses associated with thermal bridging in smaller components to be accounted for. In masonry cavity wall systems, most of the energy losses from thermal bridging are due to structural penetrations at floor levels located at the shelf...

It is difficult to join high strength alloy steel which are produced by thermo mechanical controlled processing and get overmatched properties on the welds and heat affected zone (HAZ) when submerged arc welding (SAW) is used as joining process. Circumferential welds made in the mill to join...

The effects of soil and plant nutrients on the oviposition preference, larval performance and spatial dynamics of Ceutorhynchus obstrictus and its parasitoids
DownloadFall 2010
The effects of nitrogen and sulfur fertilization on the oviposition, feeding preferences, and larval performance of Ceutorhynchus obstrictus (Marsham) (Coleoptera: Curculionidae) on Brassica napus L. were examined in a series of laboratory experiments. The associations between C. obstrictus...

The Role of Sulfur Species in Establishing the Corrosion Reactions in Refinery Metallurgies
DownloadSpring 2016
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...
