Cubic metallic alloys generally grow along 〈100〉 directions due to the anisotropy of the solid-liquid interfacial energy. Under rapid solidification conditions, dendrites may deviate from 〈100〉 and develop unusual morphologies. Here, Al-alloy droplets (Al-4.5Cu, Al-10Si, Al-1.9Fe, Al-33Cu, all in...

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...

Scandium (Sc) is an expensive alloying element which has an important effect on the properties of aluminum alloys. It is of interest to determine for a variety of solidification conditions the effect of minor addition, in the hypoeutectic levels, of Sc on Al alloys. This study builds on past work...

The Hybrid tank pilot plant was designed in Process Control Laboratory (PCL) of the University of Alberta at 2009. In this report, we try to construct a model for this process. Using the physical behavior of the plant, it is possible to have the nonlinear first principle dynamic model of that...

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

There is significant interest in designing a cryopreservation protocol for hematopoietic stem cells (HSC) which does not rely on dimethyl sulfoxide (Me2SO) as a cryoprotectant. Computer simulations that describe cellular osmotic responses during cooling and warming can be used to optimize the...

The structural performance of microalloyed steel weld joints is essentially dependent on the microstructural characteristics of the heat-affected zone (HAZ). However, the microstructure is adversely impacted by the heat input of the welding process. As such, an X70 microalloyed steel was welded...

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...
