Experiments
PART A
1 Preparation of specimen for Metallographic examination of different engineering materials. To report microstructures of plain carbon steel, tool steel, gray C.I, SG iron, Brass, Bronze & composites.
2 Heat treatment: Annealing, normalizing, hardening and tempering of steel. Metallographic specimens of heat treated components to be supplied and students should report microstructures of furnace cooled, water cooled, air cooled, tempered steel. Students should be able to distinguish the phase changes in a heat treated specimen compared to untreated specimen.
3 Brinell, Rockwell and Vickers’s Hardness tests on untreated and heat treated specimens.
4 To study the defects of Cast and Welded components using Non-destructive tests like:
d) Ultrasonic flaw detection
e) Magnetic crack detection
f) Dye penetration testing.
PART B
5 Tensile, shear and compression tests of steel, aluminum and cast iron specimens using Universal Testing Machine
6 Torsion Test on steel bar.
7 Bending Test on steel and wood specimens.
8 Izod and Charpy Tests on Mild steel and C.I Specimen.
9 To study the wear characteristics of ferrous and non-ferrous materials under different parameters.
10 Tensile, shear and compression tests of steel, aluminum and cast iron specimens using Universal Testing Machine
11 Fatigue Test (demonstration only).
Course Outcomes:
At the end of the course the student will be able to:
CO1: Acquire experimentation skills in the field of material testing.
CO2: Develop theoretical understanding of the mechanical properties of materials by performing experiments.
CO3: Apply the knowledge to analyse a material failure and determine the failure inducing agent/s.
CO4: Apply the knowledge of testing methods in related areas.
CO5: Understand how to improve structure/behaviour of materials for various industrial applications.
Conduct of Practical Examination:
1. All laboratory experiments are to be included for practical examination.
2. Breakup of marks and the instructions printed on the cover page of answer script to be strictly adhered by the examiners.
3. Students can pick one experiment from the questions lot prepared by the examiners.
4. Change of experiment is allowed only once and 15% Marks allotted to the procedure part to be made zero.
Scheme of Examination:
ONE question from part -A: 30 Marks
ONE question from part -B: 50 Marks
Viva -Voice: 20 Marks
Total: 100 Marks
