Answer and Explanation:
The crack formation growth that takes place in an environment corrosive.
Stress corrosion cracks can be defined as the spontaneous failures of the metal alloy as a result of the combined action of corrosion and high tensile stress. 
Some of the characteristic features of stress corrosion cracks are:
- These occur at high temperatures.
- Occurrence of failures in metals mechanically.
- Occurrence of sudden and unexpected failures under tensile stress.
- The rate of work hardening of the metal alloy is high.
- Time
- An environment that is specific for stress corrosion cracking.
