A Recent Trend of Materials and a Task of Railway Materials in Future


Taro TSUJIMURA
The trends in the material engineering are separating into two broad streams. One aims at the ultimate performance of materials using advanced technologies and the other is at reviewing the convetional materials to find out the most suitable combinations and applications of them. Apart from these trends, it seems likely that the idea of minimizing the impact of materials on the earth environment through these appropriate selection, is widely spreading. In the railway, it would be necessary to adopt such thinking in materials development and selection.
