Comprehensive study of the abrasive wear and slurry erosion behavior of an expanded system of high chromium cast iron and microstructural modification for enhanced wear resistance
DownloadSpring 2014
High chromium cast irons (HCCIs) have been demonstrated to be an effective material for a wide range of applications in aggressive environments, where resistances to abrasion, erosion and erosion-corrosion are required. For instance, machinery and facilities used in mining and extraction in...

Micro-modeling and study of the impact of microstructure on the performance of solid oxide fuel cell electrodes
DownloadFall 2010
As the demand for green energy and fuel cells grows, more attention is drawn towards Solid Oxide Fuel Cells (SOFCs). Random and complex structure of composite electrodes and underlying electrochemical process has not been completely unveiled yet and further study is required to acquire more...

Spring 2018
Grade 91 steel is one of the most important 9-12% Cr creep strength enhanced ferritic (CSEF) steels used in fossil-fuel fired power plants. A narrow heat-affected zone with heterogeneous structures is generated in the base metal, due to non-equilibrium phase transformations during the arc welding...

Fall 2010
The microstructures and performance of Ni-based alloys and Ni-WC (nickel-tungsten carbide) composite overlays deposited by plasma transferred arc welding have been studied. The Ni-alloy overlays had similar microstructures consisting of Ni dendrites, with interdendritic Ni-based eutectics,...

Fall 2009
This thesis deals with the mechanisms of microstructure development in polymer blends. Much work has been performed on the breakup process of immiscible systems where the dispersed phase is suspended inside another matrix. The fluids used were polymer melts or model viscoelastic fluids, and the...

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...

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 2009
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....

Spring 2012
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...
