JNTUH B.Tech 2nd Year 1 sem Chemical Engineering (2-1) Material Science for Chemical Engineering R13

JNTUH B.Tech 2nd year Material Science for Chemical Engineers gives you detail information about Material Science for Chemical Engineers Engineering R13 year subject. It will be help full you to understand you complete curriculum of the year.

Objective

This course will help students to learn about the relationship between structure and properties of
materials, application of various classes of materials including metals, ceramics, polymers.

UNIT I

Introduction: Engineering Materials – Classification – levels of structure. Crystal Geometry and Structure Determination: Space lattice and Unit cell. Bravais lattices, crystal systems with examples. Lattice coordinates, Miller indices, Bravais indices for directions and places: crystalline and non crystalline solids; ionic, covalent and metallic solids; packing efficiency, coordination number; structure determination by Bragg’s X-ray diffraction and powder methods.

UNIT II

Crystal Imperfection: Point defects, line defects-edge and screw dislocation, Berger’s circuit and Berger’s vectors, dislocation reaction, dislocation motion, multiplication of dislocations during deformation , role of dislocation on crystal properties; surface defects, dislocation density and stress required to move dislocations.

UNIT III

Basic thermodynamic functions: phase diagrams and phase transformation: Primary and binary systems general types with examples; tie line& lever rule, non equilibrium cooling: phase diagrams of Fe-Fe3-C, Pb-Sn, Cu-Ni systems. Phase transformations in Fe-Fe3-C steels, Time-Temperature-Transformation (TTT) curves for eutectoid steels and plain carbon steels; effect of alloying elements on properties of steels; types of steels, alloys and other metals used in chemical industry.
