(Common to Mechanical & Automobile)

OBJECTIVE

To impart knowledge on the structure, properties, treatment, testing and applications of

metals and non-metallic materials so as to identify and select suitable materials for

various engineering applications.

Review (Not for Exam):

Crystal structure – BCC, FCC and HCP structure – unit cell – crystallographic planes

and directions, miller indices – crystal imperfections, point, line, planar and volume

defects – Grain size, ASTM grain size number.

UNIT I CONSTITUTION OF ALLOYS AND PHASE DIAGRAMS 9(L)

carbide equilibrium diagram. Classification of steel and cast Iron, microstructure,

properties and applications.

UNIT II HEAT TREATMENT 9(L)

Definition – Full annealing, stress relief, recrystallisation and spheroidizing –normalising,

hardening and tempering of steel. Isothermal transformation diagrams – cooling curves

superimposed on I.T. diagram, CCR - Hardenability, Jominy end quench test –

carbonitriding, flame and induction hardening.

UNIT III MECHANICAL PROPERTIES AND TESTING 9(L)

Mechanism of plastic deformation, slip and twinning – Types of fracture – Testing of

materials under tension, compression and shear loads – Hardness tests (Brinell, Vickers

and Rockwell), Impact test - Izod and Charpy, Fatigue and creep tests, fracture

toughness tests.
