Integrated Computational Materials Engineering

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 Integrated Computational Materials Engineering. 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.
