Explain the difference between natural and Artificial aging. Use sketches as necessary.
Difference between natural aging and Artificial aging are
* In natural aging materials room temperature is sufficient to move unstable super saturated solution towards the stable two phase structure.
*In artificial aging elevated temperature is required to provide diffusion.
* Natural aging cannot be controlled or stopped.
*Artificial aging can be controlled and stopped by maintaining required temperature.
*Natural aging offers more flexibility.
✓Artificial aging is the process of treatment of metal alloy at elevated temperature to acclerate changes in properties of metal.
✓Natural aging is the process of aging of metals naturally with respect to time.
