Unit 1

Structure of Crystalline Solids – Interatomic Bonding – Crystal Systems – UNIT cells – Metallic Crystal Structures – Miller indices – Crystallographic planes and directions – Linear and Planar Atomic Densities – Imperfections in Solids: Point – Linear – Interfacial defects.

Elastic, Anelastic and Plastic behaviour. Mechanical properties – stress-strain curves for ductile and brittle alloys. Ductility – Resilience -toughness. Hardness testing. Dislocations and plastic deformation. Slip phenomenon. Slip in single crystals.

Unit 2

Strengthening mechanisms – grain boundary hardening, solution hardening, work hardening. Ductile and Brittle Fracture – fracture mechanics. Impact testing. Ductile – brittle transition. Fatigue and creep properties. S-N Curves Fatigue and creep testing.

Constitution of alloys-solid solution, intermetallic compound, Hume-Rothery rule. Phase diagram-phase rule, lever principle, isomorphous, eutectic, peritectic and eutectoid reactions. Iron-Carbon phase diagram, equilibrium and non-equilibrium cooling in solid state, isothermal transformation, martensite and bainite reactions.

Unit 3

Heat treatment of steels: annealing, normalizing, hardening and tempering. Heat treatment of tool and die steels. Hardenability, its testing and simple problems related to materials selection. Surface hardening of steels – carburizing, nitriding, carbo-nitriding, induction method.

Classification of cast iron and steels – properties, microstructures and uses of cast irons, plain carbon, alloy, stainless, heat resistant, tool and die steels. Composition, properties, microstructures and uses of non-ferrous alloys – brass, bronze, aluminium, magnesium, nickel and zinc alloys.
