Selection of Materials detail syllabus for Agricultural Technology (123), M scheme is taken from TNDTE official website and presented for diploma students. The course code (32681), and for exam duration, Teaching Hr/week, Practical Hr/week, Total Marks, internal marks, theory marks, duration and credits do visit complete sem subjects post given below.
For all other metallurgy 6th sem syllabus for diploma m scheme tndte you can visit Metallurgy 6th Sem Syllabus for Diploma M Scheme TNDTE Subjects. For all other ELECTIVE – II THEORY subjects do refer to ELECTIVE – II THEORY. The detail syllabus for selection of materials is as follows.
Rationale:
The selection of material most suitable for a particular component of a machine is a very important function of material engineer. To select most suitable material for a given application one who thoroughly knows a properties and behaviour of materials.
To this, the various properties of engineering material, criteria for selection and factors affecting engineering material selection are in first unit. Corrosion engineering and corrosion resistance material are in 2nd unit and high, low temperature, electrical and magnetic and nuclear engineering materials are in 3rd, 4th and 5th unit respectively. By studying this subject one who can easy to suggest the most suitable material.
Objectives:
At the end of the study of VI Semester the student will be able to
- To know the properties of engineering materials
- To know the selection criteria for engineering materials.
- Study about corrosion – its types and prevention methods.
- Learn about the corrosion resistant alloys.
- Study about the high temperature and low temperature materials.
- Learn about friction materials and its properties.
- Learn about the impact and bearing materials.
- Learn about the electrically conductive and resistance materials
- Study about the magnetic materials.
- To know about the materials used for Nuclear Engineering.
