Nevertheless, corrosion damage can be extensive where the ac currents are large. Stress-corrosion cracking (SCC) is defined as cracking of a material...

Perfection is rarely attained in general practice, and some compromise on materials limitations, both chemical and mechanical, is necessary. The difficulty is that mechanical fault can contribute to corrosion and that corrosion (as a...
