Effects of Solidification Thermal Parameters and Bi Doping on Silicon Size, Morphology and Mechanical Properties of Al 15wt.% Si 3.2wt.% Bi and Al 18wt.% Si 3.2wt.% Bi alloysDownload
The use of bismuth (Bi) in aluminum (Al) industries is recognized as prime importance because of possible recycling as alloying element in special applications such as those enhancing machinability. The effects of Bi interaction on solidification progress as well as on the resulting...
Time Dependence of Hydrogen Induced Cracking of X70 Pipeline Steel under Severe and Mild Sour Service Conditions using Ultrasonic AnalysisDownload
A standard NACE hydrogen induced crack test was used to evaluate the resistance of two compositions of X70 steel (X70-X (Ca/S ratio of 2.5) and X70-B (Ca/S ratio of <0.5)) under severe (pH = 2.7 and 100% H2S) and mild (pH = 5.5 and 100% H2S) sour service conditions. An ultrasonic technique was...
State-of-the-art iridium-based catalysts for acidic water electrolysis: a minireview of wet-chemistry synthesis methodsDownload
With the increasing demand for clean hydrogen production, both as a fuel and an indispensable reagent for chemical industries, acidic water electrolysis has attracted considerable attention in academic and industrial research. Iridium is a well-accepted active and corrosion-resistant component of...
Final Report for Creative Sentencing: Protecting Worker Safety in Alberta by Enhancing Field Level Hazard Assessments and Training for Ground Hazards Associated with Tailings Facilities, Dams, and SystemsDownload
Efforts related to the safety and performance of oil sands tailings storage and transportation facilities have traditionally focused on preventing catastrophic failures and are well defined by government legislation and industrial best practices. However, a recent death related to ground hazards...
Plasma transferred arc additive manufacturing is a growing technology in the additive manufacturing world. The plasma transferred arc additive manufacturing system’s ability to produce large samples, compared with other common additive manufacturing techniques, makes it highly desirable in many...
Preparative chromatography is an indispensable separation process in the food, pharmaceuticals and fine chemical industry. The aim of this work is to summarize developments in preparative chromatographic processes in the period 2009– 2012. Particular attention is paid to new developments in the...
The dendrite growth velocity in Al75Ni25 melts has been measured in a containerless procedure as a function of undercooling using an electromagnetic levitation technique both in the Earth laboratory and in Space on board the International Space Station. The growth shows an anomalous behavior...
This paper reports on the characterization of rapidly solidified Al-4.5 wt% Cu-xSc (x= 0.1, 0.2 or 0.4 wt %). The effect of micro-additions of Sc (up to 0.4 wt %) was examined through microstructural analysis of rapidly solidified, as well as aged samples, by means of electron microscopy, x-ray...
This paper reports on the undercooling and growth morphology of Al-4.5wt%Cu and Al-4.5wt%Cu-0.4wt%Sc with a focus on the effect of Sc addition. It is found that the addition of Sc reduces the undercoolings of both primary phase and eutectic. In addition, the morphology of the Al-4.5wt%Cu-0.4wt%Sc...
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...
