In this work, rapid solidification microstructures and mechanical properties of Al1.5Mg0.2Sc and Al3Mg0.2Sc are investigated. Samples in the form of powders and strips / deposits of different thermal histories are obtained by means of impulse atomization technique. Cooling rates of the powders,...
Microalloyed steels are a class of High Strength Low Alloy (HSLA) steels that contain a low concentration of carbon and up to 0.1% by weight of microalloying elements such as Ti, Nb, V and B. Microalloyed steels are known for their excellent combination of strength, toughness and weldability. The...
Microalloyed steels derive their superior properties from the introduction of microalloying elements (titanium (Ti), niobium (Nb), and vanadium (V)). These elements form various carbonitride particles at different stages of production. Titanium nitride (TiN) has the lowest solubility limit in the...
During the past several decades, the relationship between microstructure and mechanical properties of high strength microalloyed steels has been extensively studied in an effort to improve the fracture toughness and strength of these types of steels, without appreciably increasing steel...
Heavy gauge (>11 mm wall thickness) X70 pipe is one of the products produced using submerged arc welding (SAW) and is the subject of this thesis. The SAW process offers substantial advantages, including a high deposition rate, deep penetration, and reduced welding times. These attributes are...
Strain aging of microalloyed steel pipes, manufactured for oil and gas transmission, can occur during the anti-corrosion fusion bonded epoxy coating process (180°C - 250°C) and/or during long term storage or use. The primary mechanism of strain aging involves the segregation of interstitial...
An evaluation of the resistance of two different X70 pipeline steels to hydrogen-induced cracking in severe (pH 2.7 and 1 atm H2S) and intermediate (pH 5.5 and 1 atm H2S) sour service conditions was undertaken. The two steels used in this work, X70-X and X70-B, were selected based on their...
This thesis focuses on the manufacturing of high carbide content wear-resistant parts by extrusion- based Additive Manufacturing (AM) based on the principles of Powder Metallurgy (PM). A new manufacturing technique, termed Fused Filament Fabrication of Cermets (FFFC) is presented. First, particle...
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....
