| Research Abstract |
Computational chemistry approach was applied to study the mechanism of Stress Corrosion Cracking (SCC). Enhanced chemical reactions and diffusion of oxygen atoms due to strain were found to be one of the important factors in the crack growth process of SCC. Hafnium was suggested to be effective element for the formation of stable oxide film and the decrease of strain-enhanced oxygen diffusion.
