BMM OE8 03 - ENGINEERING MATERIALS
Module I (10 Hours)
Introduction, Metals: the generic metals and alloys; iron-based, copper-based, nickel-based, aluminum-based and titanium-based alloys. Metal
structures the range of metal structures that can be altered to get different properties: crystal and glass structure, structures of solutions and
compounds, grain and phase boundaries, equilibrium shapes of grains and phases.
Module II (10 Hours)
The light alloys where they score over steels; how they can be made stronger: solution, age and work hardening; thermal stability; Alloy steels
adding other elements gives hardenability (ease of martensite formation), solution strengthening, precipitation strengthening, corrosion resistance,
and austenitic (f.c.c.) steels; Introduction: Ceramics and glasses: the generic ceramics and glasses: glasses, vitreous ceramics, high-technology
ceramics.
Module III (10 Hours)
cements and concretes, natural ceramics (rocks and ice), ceramic composites; Structure of ceramics, crystalline ceramics; glassy ceramics; ceramic
alloys; ceramic micro-structures: pure, vitreous and composite; The mechanical properties of ceramics high stiffness and hardness; poor toughness
and thermal shock resistance; the excellent creep resistance of refractory ceramics.
Module IV (10 Hours)
Introduction: Polymers and composites Polymers the generic polymers: thermoplastics, thermosets, elastomers, natural polymers; The structure of
polymers giant molecules and their architecture; molecular packing: amorphous or crystalline?; Mechanical behavior of polymers how the modulus
and strength depend on temperature and time; making giant molecules by polymerisation; polymer “alloys”; Composites: fibrous, particulate and
foamed how adding fibres or particles to polymers can improve their stiffness, strength and toughness; why foams are good for absorbing energy.
