1. Atomic structure of metals & crystal system, crystallographic notation of atomic planes,

polymorphism and allotropy, solidification of crystallization (i) nuclear formation (crystal growth) (ii)

crystal imperfection Elementary treatment of theories of plastic deformation, phenomenon of slip

twinning, dislocation, identification of crystallographic possible slip planes and direction in FCC, BCC,

C.P., recovery, re-crystallization, preferred orientation causes and effects on the property of metals.

2. General principles of phase transformation in alloys, phase rule and equilibrium diagrams,

Equilibrium diagrams of (i) Binary system in which the components form a mechanical mixture of

crystals in the solid state and are completely mutually soluble in both liquid state. (ii) systems whose

components have complete mutual solubility in the liquid state and limited solubility in the solid state

in which the solid state solubility deceases with temperature(iii) alloys whose components have

complete mutual solubility in the liquid state and limited solubility in solid state (iv) system whose

components are subject to allotropic change. Iron carbon equilibrium diagram and their Phase

transformation

3 Engineering materials and their properties, classification. Classification of ferrous and non-ferrous

materials. Classification of cast iron-properties and their applications. Effects of alloying elements on

properties of steel, carbon steel, low alloy steels, stainless steel, tool steels and die steels. Alloys of

Ni, Al, Cu, Mg; properties and their applications. Classification of composite materials and their

properties and applications.

4. Heat treatment and surface treatment: Heat treatment of steel – Annealing, Normalising, Hardening

and tempering with their types and application to automotive components, surface hardening

techniques, Induction, flame and chemical hardening, coating of wear and corrosion resistance,

Electroplating. Phosphating, Anodizing, hot dipping, thermal spraying, hard facing and thin film
