»ã±¨ÄÚÈݼò½é£ºThe mission of Materials Genome Initiative (MGI) is to reduce the cost and development time of materials discovery, optimization, and deployment. Traditional trial-and-error-based experimental approach to screen potential candidates for a desired new application is very expensive and time-consuming. This is largely because the task of designing a new material is extremely complex, involving many factors that must be balanced. A few percent change in composition or slight modification in manufacturing processes can alter critical qualities significantly, while the investigation of all possible variations of the composition and manufacturing processes of such alloys would be prohibitively expensive due to the involvement of numerous tests of these properties. Computational materials by design has emerged as an effective approach for accelerating materials design and process optimization.

The Pandat software package and thermodynamic databases developed at CompuTherm are currently being used by hundreds of users worldwide. Especially, CompuTherm’s modeling tools are now being used by the US Air Force, NASA, aerospace industries including GE, P&W, and Rolls-Royce, and automobile industries, such as GM and Ford. The use of these modeling tools has resulted in shorter development cycles and significant cost savings through the elimination of shop/laboratory trials and tests.
