Spring 2010
Tungsten carbide-based metal matrix composite coatings are deposited by PTAW (Plasma Transferred Arc Welding) on production critical components in oil sands mining. Homogeneous distribution of the reinforcement particles is desirable for optimal wear resistance in order to reduce unplanned...

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....

Fall 2023
A thermal-microstructural model was developed to predict the effect of laminar cooling during TMCP on the through thickness microstructure of an X70 steel. Model development was conducted in three sections, beginning with microstructure modelling of dilatometer samples with cooling rates ranging...

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...

Modelling of the Thermal History During Submerged Arc Welding and Wire and Arc Additive Manufacturing
DownloadSpring 2023
The finite element method (FEM) and finite element analysis (FEA) are numerical techniques to solve partial differential and ordinary differential equations. They are widely used in engineering, physics, and other fields. The development of these FEM and FEA makes it possible to accurately...

Spring 2013
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...

Fall 2011
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...

Spring 2018
Microalloyed steels and heat treated steels are widely used in the pipeline industry. Microalloyed steels are a type of high strength low alloy steels containing small additions of C, N, Nb, Ti and other elements in amounts less than 0.1 wt%. They may also contain additions of other elements in...

Quantification of Coarse TiN-rich Precipitates in High Ti Microalloyed Steels Using EMPA Mapping and SEM/EDX
DownloadSpring 2024
Microalloyed steels are high strength steels with low alloying additions of Ti, Nb, and V. These microalloying elements form carbonitride precipitates during thermomechanical controlled processing (TMCP), which enhance the mechanical properties of steel. TiN is one of the first precipitates to...
