Development of a diffusion database

A database of diffusion in solid on WWW is under development with the aim o f supporting research activities on diffusion phenomena or materials design . It covers diffusion in metals and nuclear materials such as iron-, nickel -, or zirconium-alloys, and titanium alloys. The user interface and the fun ctions are designed intelligibly, which enables even beginners to use this database properly. Some analyses by statistical approach have been performe d to classify retrieved data with utilizing the functions of the system. Th e result shows that candidates for parameters to classify data and influent ial factors in isolated data can be suggested. A new advanced function base d on this approach has been designed.
