Rapid failure of metallic materials by an interaction between cyclic loading ( tensile stresses) and the presence of a corrosive environment the material has no (too little) resistance against. also when the corrosion scale is more brittle then the substrate and cracking in the (protective) scale occurs.
Initiation by corrosion causes local stress raisers and fine cracking which exposes a fresh metal surface, ready to corrode at the crack tip.
The generated corrosion product may act as a wedge generating additional forces to the metal. In general straight cracks develop perpendicular to the stresses.
Thermal (cyclic) stresses may result in a cracked earth pattern cracking ( surface appearance) since these stresses are randomly distributed over the materials surface, the cracks run perpendicular into the material.

Where is it possible to learn about corrosion?
A great starting point to learn about corrosion is on the National Corrosion Society web page. They provide in-depth explanations of what corrosion is and how it forms. They also provide monthly newsletters on the latest developments to fight corrosion.
Is corrosion of aluminum metal a chemical?
Corrosion is a chemical process.
When was Corrosion of Conformity created?
Corrosion of Conformity was created in 1982.
When is corrosion useful?
Corrosion can be useful for creating materials that have specific properties, such as rust on iron that can act as a protective barrier. In some cases, controlled corrosion can be used to achieve desired aesthetics in art and architecture. Additionally, corrosion processes can be harnessed for energy generation, such as in fuel cells.
Is ease of corrosion a physical change or a chemical change?
The ease of corrosion of resistance to corrosion is a chemical property and not a physical one. Corrosion is a chemical change which changes the identity of the substance.
