The assembly of colloidal particles from evaporating suspension drops is seen as a versatile route for the fabrication of supraparticles for various applications. However, drop contact line pining leads to uncontrolled shapes of the emerging supraparticles, hindering this technique. Here we...

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 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...

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...

Pipeline failures can be severe events that impact both society and industry. The oil spills in North Battleford, Saskatchewan in 2016 and the gas rupture in Beardmore, Ontario in 2011 are examples of recent pipeline failures in Canada. Pipeline failures have led to pipe fabricators developing...

Wiskel, J.B., Li, X., Ivey, D.G., Henein, H.
Quantitative X-ray diffraction characterization of four (4) X80 and three (3) X100 microalloyed steels was undertaken. The effect of through thickness position, processing parameters and composition on the measured crystallite size, microstrain and J index (relative magnitude of crystallographic...

Wiskel, J.B., Ma, J., Ivey, D.G., Henein, H.
Transverse tensile samples were extracted from the centreline position of three different compositions of uncoated thick walled microalloyed X70 UOE pipe at a location 180° from the weld. Aging heat treatments of 5, 15, and 25 minutes and temperatures of 175, 215, and 255°C were applied. Tensile...

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...
