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 non-ideal osmotic equilibrium equation is proposed as a replacement for the Boyle van’t Hoff equation to describe the equilibrium volume of a living cell as a function of external osmolality. Contrary to common understanding, the Boyle van’t Hoff equation is only valid for ideal, dilute...

This paper investigates amorphous phase formation and rapid solidification characteristics of a CoCr alloy. High cooling rate and high undercooling-induced rapid solidification of the alloy was achieved by impulse atomization in helium atmosphere. Two atomization experiments were carried out to...

The multisolute osmotic virial equation is the only multisolute thermodynamic solution theory that has been derived from first principles and can make predictions of multisolute solution behaviour in the absence of multisolute solution data. Other solution theories either (i) include simplifying...

Wiskel, J.B., Linchieh, A., Henein, H.

A series of infrared temperature videos were taken of the upper surface of hot rolled microalloyed steel skelp immediately following laminar cooling. In addition to validation of the skelp temperature and skelp cooling patterns, local temperature minimums were observed in the infrared images....

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...

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...

The Impulse Atomization process developed at the University of Alberta (Canada) enables metallic powders to be solidified with well controlled process parameters. The inner microstructure of several droplets of Al-4.5wt.%Cu alloy produced by this technique has been investigated by using both...

High strength low carbon microalloyed steels may be adversely affected by the high heat input and thermal cycle that they experience during tandem submerged arc welding (TSAW). The heat affected zone (HAZ), particularly the coarse grained heat affected zone (CGHAZ), i.e., the region adjacent to...
