“Meso-scale multi-physics modelling of industrial solidification processes”

Abstract:

Meso-scale models based on granular materials are finding use in gaining understanding of defect formation mechanisms during metallic-alloy solidification processes. In this talk, research is presented on the use of meso-scale models for predicting hot tearing/solidification cracking in aluminum alloy casting and welding processes. These models couple solidification modules, mechanical deformation modules, fluid-flow modules, and defect modules in order to first construct the microstructure of the semi-solid, second to simulate deformation and intergranular flow, and finally to comprehensively predict crack formation. Examples will be given for the binary Al-Cu, A356, and AA6061 alloy systems.

Biography:

Dr. Phillion received his PhD from the Department of Materials Engineering at The University of British Columbia in 2007, where he combined high temperature experimental methods with multi-scale modelling to investigate solidification processes and casting defects. After completing his PhD, he spent two years (2008-2009) as a Post-doctoral fellow at EPFL, Switzerland in the LSMX Computational Materials, followed by six years (2010-2015) as a faculty member in the School of Engineering at The University of British Columbia’s Okanagan campus. He joined McMaster University in 2016.
