MSE Colloquium: Jianzheng Guo, ICME of Casting Design and Development --From CALPHAD to process/defects/microstructure simulation and mechanical property prediction

Abstract

Integrated Computational Materials Engineering (ICME) is emerging as a methodology for developing advanced materials, manufacturing processing, and engineering components in a faster and more cost effective way. For casting processes, ICME involves many physical phenomena such as thermodynamics, heat transfer, fluid flow, stress, defect formation, microstructure evaluation, and thermophysical and mechanical properties.

The integration of thermodynamic calculations, thermophysical and mechanical property predictions, and the prediction of microstructure and defects during solidification and heat treatment will be presented. Such integration is helpful to understand the effects of alloy chemistry and processing conditions, and their relationship to microstructure, defect formation, and the final mechanical properties from solidification to heat treatment. Eventually the alloy chemistry and processing parameters can be optimized with the help of the integrated computational modelling.

Jianzheng Guo has over 23 years of experience in modeling of casting and solidification. He has worked with leading companies like GE (2007 to 2008) and ESI (2000 to 2007 and 2008 to Present) as a senior scientist. He has extensive experience in CALPHAD, process/defect/microstructure modeling and mechanical property prediction on metals.

Jianzheng has a Ph.D. from The University of Iowa, Master and Bachelor of Engineering in Mechanical Engineering from Tsinghua University, China. He published number of his works as Journal papers as well as book chapters. As one of the instructors, he taught ICME short course at AIAA and AeroMAT conferences.
