JNTUK B.Tech Materials Science & Engineering gives you detail information of Materials Science & Engineering R13 syllabus It will be help full to understand you complete curriculum of the year.
Learning objectives: This subject is intended to
- provide all the technical/engineering inputs to the learner to choose or select a suitable materials of construction of chemical/petrochemical process equipment, piping and internals each device/components has its own specific usage under different process environmental conditions: the course helps the learner.
- judiciously choose the material so that it meets the specific life expectancy by redusing the shutdown frequency.
- minimize the equipment breakdown and increasing the on-stream factor.
- Choose / select the material such that it withstands the severe process operating conditions such as cryogenic, high temperature, high pressure, acidic, basic, stress induced chemical/petrochemical environments keeping view the reliability and safety of the process equipment.
UNIT-I: Classification of engineering materials, Levels of Structure, Structure-Property relationships in materials, Crystal Geometry and non-crystalline (amorphous) states. Lattice -Bravais lattices, crystal systems with examples. Lattice co-ordinates, Miller and Miller- Bravais Indices for directions and places: ionic, covalent and metallic solids; packing factors and packing efficiency, ligancy and coordination number. Structure determination by Brag’s X-raydiffraction method.
UNIT-II: Crystal Imperfections-classification-point defects-estimation of point defects-Dislocations- classification(edge and screw)-surface defects -dislocation motion and its relevance to mechanical and chemical properties –stress-strain relationship and diagrams for different materials(metals, non-metals, rubbers and plastics and polymers)-elastic and plastic deformation- slip -stress required to move a dislocation. Multiplication of dislocations –dislocation reactions, effect on mechanical behavior of materials. Strain hardening/work hardening –dynamic recovery and recrystallization.
UNIT-III: Fracture and failure of materials: ductile fracture analysis-brittle fracture analysis-fracture toughness-ductile-brittle transition-fatigue fracture-theory, creep and mechanism –methods to postpone the failure and fracture of materials and increase the life of the engineering components/structures.
UNIT-IV: Solid –liquid and solid-solid equilibria formetals and alloys. Phase rule-phase diagram for pure metals (single component system), alloys (binary systems)-micro structural changes during cooling-Lever rule and its applications-typical phase diagrams-homogeneous and heterogeneous systems, formation of Eutectic, Eutectoid mixtures- non-equilibrium cooling. Binary Systems (phase diagrams) for study: Cu-Ni,Bi-Cd,Pb-Sn, Fe-C ,Al-Cu
UNIT-V: Materials for chemical and petrochemical industrial process equipment- Effect of alloying on mechanical and chemical behavior of materials, applications of heat treatment methods for strengthening of engineering materials.
Composite structures and their advantages over conventional materials–Matrix-reinforcement properties and evaluation of strength properties with different orientation of reinforcement- applications –Nano materials –synthesis and characterization.
UNIT-VI : Stability criteria of materials in chemical/petrochemical industrial environments. Corrosion and Oxidation of materials –basic mechanisms-types of corrosion, Corrosion testing and evaluation Prevailing methods to combat corrosion. Coatings –metallic non-metallic, passivity, cathodic protection.
Out Comes
After the course, the students will be
- equipped with knowledge to prepare material selection diagram, evaluation of equipment life and prediction of life of the equipment.
- acquiring the abilities to carryout reliability studies.
- ready to carryout equipment failure analysis and propose the remedial measures.
