Abstract
A database of diffusion in solid on WWW is under development with the aim of 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 functions are designed intelligibly, which enables even beginners to use this database properly. Some analyses by statistical approach have been performed to classify retrieved data with utilizing the functions of the system. The result shows that candidates for parameters to classify data and influential factors in isolated data can be suggested. A new advanced function based on this approach has been designed.
