OBJECTIVE
The subject introduces the correlation of properties of materials and their structure. It
revises student’s knowledge of crystal structure and phase diagrams of various alloy
systems. The course not only covers metals, mainly ferrous and non-ferrous alloys, but
also structures and properties of ceramics, polymers and composites.
UNIT I STRUCTURE OF MATERIALS 8
Structure of atom – Atomic models – Bonding in solids – Bonding forces and energies –
Ionic, Covalent, metallic and van der Waals Bond - Crystal structure - Unit Cell –
Bravais lattice – BCC – FCC – HCP - Interstitial sites – NaCl crystal – CsCl crystal –
Perovskite structure – Diamond structure – Graphite – Crystal directions and planes.
UNIT II STRUCTURE OF METALS AND ALLOYS 8
Imperfection in crystals – Point defects – Dislocations – Slip plane – Movement of
dislocations – Planar defects and grain boundaries – solid solutions – Hume Rothery
rule – Phase diagram – Lever rule – Gibb’s phase rule – Phase diagram for binary alloys
– Eutectic – Peritectic – Eutectoid – Zone refining.
UNIT III FERROUS AND NON FERROUS ALLOYS 10
Allotropy and phase change of pure iron – Classification of steels and cast iron – iron –
carbon equilibrium diagram – Microstructure of iron and steel - Ferrous alloys and their
applications –Heat treatment - Factors affecting conductivity of a metal – Electrical
Resistivity in alloys – Thermal conductivity of metals and alloys – Silver, Copper and
aluminum – High Resistivity alloys – nichrome, manganin, constantan and kanthal and
their composition and applications – Super hard materials - Tungsten carbide and Boron
nitrides.
UNIT IV CERAMIC AND COMPOSITE MATERIALS 10
Advanced Ceramic Materials - Crystal Structures - Silicate Ceramics - Glasses – Glass
Ceramics – Functional properties and applications of ceramic materials – Classification
of composites - Fiber reinforced materials – Law of mixtures – Continuous fibers –
discontinuous fibers – Particle-reinforced materials – Cermets – Dispersion strengthened
materials – Laminates - Application of composites in electrical and mechanical
components – nuclear industry.
UNIT V POLYMER MATERIALS 9
Classification of polymer – Mechanisms of polymerisation - Some commercially
important individual polymer – Thermoplastics - Elastomers – Thermosets –
Engineering plastics - Liquid crystal polymers - Conductive polymers – High
