Construction and application of materials database for non-equilibrium andmetastable phases

The Institute for Materials Research, Tohoku University (IMR) is a collabor ative research institute and open to scientists all over the world. Researc h subjects of IMR covers most advanced materials of non-equilibrium and/or metastable phases. In order to contribute an original materials database on these research subjects, a comprehensive project was started in 1987. As a result of 11 years of continuous effort, an integrated database system con sisting of both literature and numerical factual databases has been constru cted and become one of the largest systems in Japanese universities. This p aper introduces the details of the management systems, utilization interfac es and contents of the database system, as well as the future IMR database projects.
