MF9211 ADVANCED MATERIALS TECHNOLOGY            

UNIT  I ELASTIC AND PLASTIC BEHAVIOR    

Elasticity in metals and polymers Anelastic and visco-elastic behaviour – Mechanism of
plastic deformation and non metallic shear strength of perfect and real crystals  –
Strengthening mechanisms, work hardening, solid solutioning, grain boundary
strengthening, poly phase mixture, precipitation, particle, fibre and dispersion
strengthening.  Effect of temperature, strain and strain rate on plastic behaviour – Super
plasticity – Deformation of non crystalline materials.

UNIT  II FRACTURE BEHAVIOUR                  

Griffith’s theory, stress intensity factor and fracture toughness  – Toughening
mechanisms  – Ductile, brittle transition in steel  – High temperature fracture, creep  –
Larson Miller parameter  – Deformation and fracture mechanism maps – Fatigue, low
and high cycle fatigue test, crack initiation and propagation mechanisms and Paris law.
Effect of surface and metallurgical parameters on fatigue  – Fracture of non metallic
materials – Failure analysis, sources of failure, procedure of failure analysis.

UNIT   III SELECTION OF MATERIALS                    

Motivation for selection, cost basis and service requirements – Selection for mechanical
properties, strength, toughness, fatigue and creep  – Selection for surface durability
corrosion and wear resistance – Relationship between  materials selection and
processing – Case studies in materials selection with relevance to aero, auto, marine,
machinery and nuclear applications – Computer aided materials selection.

UNIT  IV MODERN METALLIC MATERIALS                          8
Dual phase steels, High strength low alloy (HSLA) steel, Transformation induced
plasticity (TRIP) Steel, Maraging steel, Nitrogen steel  – Intermetallics, Ni and Ti
aluminides – smart materials, shape memory alloys – Metallic glass and nano crystalline
materials.

UNIT  V NON METALLIC MATERIALS         7
Polymeric materials – Formation of polymer structure – Production techniques of fibers,
foams, adhesives and coating – structure, properties and  applications of engineering
polymers – Advanced structural ceramics, WC, TIC, TaC, Al2O3, SiC, Si3N4 CBN and
diamond – properties, processing and applications.
