Aim Of Objectives:
The main learning objective of this course is to prepare students for:
- Having necessary background to design/select the necessary heat treatment for attaining the appropriate microstructure for the desired properties.
- Getting a comprehensive understanding of the various transformation reactions associated with the changes in microstructures and properties that occur due to controlled heat treatment.
- Understanding different case hardening techniques used in industries.
- Distinguishing the various Heat treatment furnaces, Quenching media and the heat treatment of some special alloys.
- Getting an insight on the heat treatments employed for special alloys.
