What is defined as the growth of crack formation in a corrosive environment influenced by tensile stress?

The growth of crack formation in a corrosive environment influenced by tensile stress is known as stress corrosion cracking (SCC). This phenomenon occurs when a susceptible material is exposed to both a corrosive environment and tensile stresses, leading to the initiation and propagation of cracks. These cracks can develop over time, often at stress concentrations or surface defects, and can significantly compromise the material's integrity and safety.

Stress corrosion cracking specifically requires both environmental and mechanical factors, whereby the presence of the corrosive medium enhances the material's susceptibility to crack growth under tension. Understanding this interplay is critical for assessing material failure risks in engineering applications, particularly in components subjected to high stress and harsh chemical exposures.
