For all other metallurgy 4th sem syllabus for diploma m scheme tndte you can visit Metallurgy 4th Sem Syllabus for Diploma M Scheme TNDTE Subjects. The detail syllabus for heat treatment of metals and alloys is as follows.
Rationale:
Heating plays an important role in improving the properties of steel, non ferrous metals and to some extent in cast iron. By using this heating and controlled cooling can improve the properties like hardness, strength, ductility and elongation significantly.
The syllabus for heat treatment is designed such that the student knows the basic processes in HT in first 2 units. He also knows the basic problems in processes in the 3rd unit. In the fourth and fifth units the students are prepared to know how the various properties in the ferrous and non ferrous can be improved.
Objectives:
At the end of the study of III Semester the student will be able to
- To learn about the Steel Region of the Iron-Carbon Phase Diagram
- To know about the Isothermal transformation
- To know about the Hardenability, Cooling Media, Austempering and Martempering
- To know about the Annealing, Normalising, Hardening and Tempering Processes.
- To know about the different Case Hardening Processes
- To know about the Oxidation of steel, Decarburisation of steels and remedy
- To know about the Finishing operations after heat treatment and Control of heat treating processes.
- To know about the Heat treatment of Rolled Products, Wires, Steel and Iron Castings.
- To know about the Heat treatment of forgings of shafts and axles, Springs and Gears.
- To know about the Heat treatment of Copper base alloys.
- To know about the Heat treatment of Aluminium base alloys.
- To know about the Heat treatment of Magnesium base alloys.
