报告内容摘要：

Integrated Computational Materials Engineering (ICME) is a new and potentially transformational discipline within the materials profession. At its core, ICME is the develop and utilization of material models which capture our quantitative knowledge of processing-structure-property relationships for use by the engineering community. It has the ability to unify analysis of manufacturing, design and materials into a holistic system. It offers a solution to the industrial need to quickly develop durable components at the lowest possible cost. It has the potential for accelerating development of new materials. This talk will describe Virtual Aluminum Castings, the Ford experiment in ICME. VAC is a comprehensive, integrated and experimentally verified suite of CAE tools for optimization of cast aluminum components and processes. This talk will review recent progress in integrating models for the Al-Si-Cu alloys typically used in automobile engine structures, including models for phase equilibria and microsegregation, aging response, and the influence of microstructure on properties. VAC captures this extensive knowledge of aluminum casting and provides it to a global engineering workforce. Using VAC, cast components are now designed and virtually cast, heat treated and tested for durability, all on a workstation long before components are fabricated. Future prospects for ICME, including extension of this concept to other material and manufacturing systems will also be discussed.

John E. Allison博士简介 ：

John E. Allison is a Senior Technical Leader at Ford Research and Advanced Engineering, Ford Motor Company in Dearborn, Michigan where he currently leads teams focused on the science and technology required for low cost, durable components fabricated from cast aluminum and magnesium alloys. A major focus of Dr. Allison's work is the development of integrated computational materials engineering tools. Dr. Allison has been at Ford Research Laboratories since 1983. His work experience prior to that included service as an officer in the US Air Force at the Wright Aeronautical Laboratories and a Visiting Scientist at the Brown-Boveri Corporate Research Center in Baden Switzerland. Dr. Allison is also an Adjunct Professor of Materials Science and Engineering at The University of Michigan. He has over 150 publications and 5 patents. Dr. Allison was the 2002 President of The Minerals, Metals and Materials Society (TMS) a 10,000 member global technical society for materials professionals. He currently is Vice-Chair of the NMAB Committee on Integrated Computational Materials Engineering and Chair of the TMS Technical Coordination Group for ICME. He is a Fellow of ASM, a past-member of the National Materials Advisory Board and his awards include the SAE Arch T. Colwell Award, Henry Ford Technology Award, Ford Technical Achievement Awards, Ford Innovation Awards and the Air Force Systems Command Scientific Achievement Award. Dr. Allison achieved his PhD in Metallurgical Engineering and Materials Science from Carnegie-Mellon University, his MS in Metallurgical Engineering from The Ohio State University and his BS in Engineering Mechanics from the US Air Force Academy.
