                                                UNIT I CRYSTALLOGRAPHY 
Crystal structures: BCC, FCC and HCP – directions and planes – linear and planar densities –
crystal imperfections- edge and screw dislocations – grain and twin boundaries – Burgers
vector and elastic strain energy- Slip systems, plastic deformation of materials –
Polymorphism – phase changes – nucleation and growth – homogeneous and heterogeneous

                                         UNIT II PHASE DIAGRAMS 
Phase equilibrium – solubility limit – solid solution (interstitial and substitution) – intermediate
phases – intermetallics – electron compound – Gibbs phase rule – Unary phase diagram (Iron) –
Binary phase diagrams: Isomorphous systems (Cu-Ni) – determination of phase composition
and phase amounts – tie line and lever rule – binary eutectic diagram will no solid solution and
limited solid solution (Pb-Sn) – eutectoid and peritectic reactions – other invariant reactions –
microstructural development during the slow cooling eutectic, hypereutectic and hypoeutectic

Classical free electron theory – Expression for electrical conductivity – Thermal conductivity,
expression – Quantum free electron theory :Tunneling – degenerate states – Fermi- Dirac
statistics – Density of energy states – Electron in periodic potential – Energy bands in solids
– tight binding approximation – Electron effective mass – concept of hole. Magnetic
materials: Dia, para and ferromagnetic effects – paramagnetism in the conduction electrons in
metals – exchange interaction and ferromagnetism – quantum interference devices – GMR
