ME6403 ENGINEERING MATERIALS AND METALLURGY
OBJECTIVES:
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.
UNIT I ALLOYS AND PHASE DIAGRAMS
Constitution of alloys – Solid solutions, substitutional and interstitial – phase diagrams, Isomorphous,
eutectic, eutectoid, peritectic, and peritectoid reactions, Iron – carbon equilibrium diagram.
Classification of steel and cast Iron microstructure, properties and application.
UNIT II HEAT TREATMENT
Definition – Full annealing, stress relief, recrystallisation and spheroidising – normalising, hardening
and Tempering of steel. Isothermal transformation diagrams – cooling curves superimposed on I.T.
44 diagram CCR – Hardenability, Jominy end quench test - Austempering, martempering – case
hardening, carburizing, Nitriding, cyaniding, carbonitriding – Flame and Induction hardening – Vacuum
and Plasma hardening. .
UNIT III FERROUS AND NON-FERROUS METALS
Effect of alloying additions on steel- α and β stabilisers– stainless and tool steels – HSLA, Maraging
steels – Cast Iron - Grey, white, malleable, spheroidal – alloy cast irons, Copper and copper alloys –
Brass, Bronze and Cupronickel – Aluminium and Al-Cu – precipitation strengthening treatment –
Bearing alloys, Mg-alloys, Ni-based super alloys and Titanium alloys.
UNIT IV NON-METALLIC MATERIALS
Polymers – types of polymer, commodity and engineering polymers – Properties and applications of
various thermosetting and thermoplastic polymers (PP, PS, PVC, PMMA, PET,PC, PA, ABS, PI, PAI,
PPO, PPS, PEEK, PTFE, Polymers – Urea and Phenol formaldehydes)- Engineering Ceramics –
Properties and applications of Al2O3, SiC, Si3N4, PSZ and SIALON –Composites-Classifications- Metal
Matrix and FRP - Applications of Composites.
UNIT V MECHANICAL PROPERTIES AND DEFORMATION MECHNISMAS
Mechanisms of plastic deformation, slip and twinning – Types of fracture – Testing of materials under
tension, compression and shear loads – Hardness tests (Brinell, Vickers and Rockwell), hardness
tests, Impact test lzod and charpy, fatigue and creep failure mechanisms.
OUTCOMES:
Upon completion of this course, the students can able to apply the different materials, their
processing, heat treatments in suitable application in mechanical engineering fields.
