A simplified three-phase model of equiaxed solidification for the prediction of microstructure and macrosegregation in castings
(Journal article, 2018)Macrosegregation is a result of the interplay of various transport mechanisms, including natural convection, solidification shrinkage, and grain motion. Experimental observations also indicate the impact of grain morphology, ... -
A Thermodynamic Study on the Effect of Solute on the Nucleation Driving Force, Solid?Liquid Interfacial Energy, and Grain Refinement of Al Alloys
(Journal article, 2018)Chemical composition is known to have significant effects on the grain refinement behavior of inoculated Al alloys during solidification. In this study, the influences of solute contents on the thermodynamic nucleation ... -
Application of an Equiaxed Grain Growth and Transport Model to Study Macrosegregation in a DC Casting Experiment
(Peer reviewed; Journal article, 2019)A simplified three-phase, multiscale macrosegregation model which describes the growth kinetics of equiaxed grains and the coupling between microstructure morphology and the macroscopic transport has been proposed previously. ... -
Characterizing hardening on annealing of cold-rolled aluminum AA3103 strips
(Journal article; Peer reviewed, 2013)AA3103 aluminum strips were cold rolled to various von Mises strains up to 4.7. In addition, two severely deformed conditions were obtained by one and four cycles of cold accumulated roll bonding subsequent to cold rolling ... -
Investigation of Macrosegregation Formation in Aluminium DC Casting for Different Alloy Systems
(Journal article, 2018)Direct chill (DC) casting of aluminum involves alloys employing different solute elements. In this article, a qualitative analysis and comparison of macrosegregation formation is presented for three different alloy systems: ... -
On the Effect of Atoms in Solid Solution on Grain Growth Kinetics
(Journal article; Peer reviewed, 2014)The discrepancy between the classical grain growth law in high purity metals (grain size D∝t1/2D∝t1/2) and experimental measurements has long been a subject of debate. It is generally believed that a time growth exponent ... -
Precipitation of Non-Spherical Particles in Aluminum Alloys Part I: Generalization of the Kampmann–Wagner Numerical Model
(Journal article, 2015)Particles precipitated during aging treatments often have non-spherical shapes, e.g., needles or plates, while in the classical Kampmann–Wagner Numerical (KWN) precipitation model, it is assumed that the particles are of ... -
The Effect of Solute Atoms on Grain Boundary Migration: A Solute Pinning Approach
(Journal article, 2013)The effect of solute atoms on grain boundary migration has been modeled on the basis of the idea that solute atoms will locally perturb the collective rearrangements of solvent atoms associated with boundary migration. The ... -
Vacuum evaporation of pure metals
(Journal article; Peer reviewed, 2013)Theories on the evaporation of pure substances are reviewed and applied to study vacuum evaporation of pure metals. It is shown that there is good agreement between different theories for weak evaporation, whereas there ...
