In the metal component of structures, various modes of deterioration occur due to corrosive environments, high and low temperatures, and the generation of stress conditions. Metal deterioration is engineering risk since facilities in industrial plants and a components of infrastructure have now aging issue. Hence, metal deterioration has to be properly managed to prevent accidents due to resulting changes in metal structure.

To achieve this, studies are needed on innovative materials and the mechanisms of metal deterioration, such as corrosion, crack propagation analysis, advanced nondestructive evaluation, and maintenance technologies. deterioration is engineering risk since facilities in industrial plants and a components of infrastructure have now aging issue. Hence, metal deterioration has to be properly managed to prevent accidents due to resulting changes in metal structure.

The aim of this Special Issue is to share solutions to the problem of metal deterioration, including through theoretical and experimental studies. We expect contributions to the Special Issue from scholars and researchers all over the world from both academic and industrial fields. deterioration is engineering risk since facilities in industrial plants and a components of infrastructure have now aging issue. Hence, metal deterioration has to be properly managed to prevent accidents due to resulting changes in metal structure.

We previously proposed a statistical risk analysis method for accidents at industrial facilities
by using a risk curve to show the relationship between the cumulative frequencies and
the damage magnitude of the accidents on a log-log scale.



I am always looking for collaborative work with oversea research institutes.
