Question

Explain 3 diff types of Stress Corrosion Cracking

Answer 1

Stress corrosion cracking is a type of corrosion that occurs in the presence of tensile stress and a corrosive environment. There are three main types of stress corrosion cracking: transgranular, intergranular, and hydrogen-induced.

Step-by-step explanation:

Stress corrosion cracking is a type of corrosion that occurs in the presence of tensile stress and a corrosive environment. There are three main types of stress corrosion cracking:

1. Transgranular stress corrosion cracking: This type of cracking occurs along the grain boundaries of a material. It is commonly observed in metals like stainless steel and aluminum alloys.
2. Intergranular stress corrosion cracking: This type of cracking occurs within the grains of a material. It is typically seen in materials that are sensitive to intergranular corrosion, such as certain stainless steels and brass.
3. Hydrogen-induced stress corrosion cracking: This type of cracking is caused by the interaction of atomic hydrogen with a material under tensile stress. It is commonly observed in high-strength steels and titanium alloys.

Each type of stress corrosion cracking has its own specific mechanisms and characteristics, but they all involve the interaction of stress, corrosive environment, and material composition.
