Spinelli, J.E., Hearn, W., Bogno, A.-A., Henein, H.
Understanding the influence of rapid solidification conditions on the formed microstructure is important to determine how process conditions affect the final mechanical properties. In this work the rapid solidification of hypoeutectic and hypereutectic Al-xSi (x=10wt. %, 18wt %) alloys was...

A Study of Rapidly Solidified Al1.5wt%/3wt%Mg0.2wt%Sc Powders and Strips using Impulse Atomization
DownloadFall 2016
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,...

Mohammadijoo, M., Collins, L., Henein, H., Ivey, D.G.
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...
