Behaviour of stress corrosion cracking of austenitic stainless steels in sodium chloride solutions
Samir Milad, Elsariti; Haftirman, Dr. (Malaysian Technical Universities Network (MTUN), 2012-11-20)Click Stress Corrosion Cracking (SCC) is an environmentally well-known as a failure caused by exposure to a corroding while under a sustained tensile stress. SCC is most often rapid, unpredictable. Failure can occur in a ... -
