Course

Unit 1

Basics of Materials Structure: crystal systems – space lattice – miller indices of atomic planes and directions – small problems in crystallography – crystal defects point, line and surface defects. Mechanical Behaviour of Materials: stress-strain curve – elastic deformation – characteristics of elastic deformation – atomic mechanism of elastic deformation – inelastic deformation – strain time curves – viscous deformation – plastic deformation – slip and twinning – Schmidt’s law – critical resolved shear stress – Strengthening mechanisms; work hardening – grain boundary hardening, dispersion hardening.

Unit 2

Mechanical Testing and Fracture of Materials: Tensile test – stress–strain curves for ductile and brittle materials – proof stress – Compression test – Hardness test – Impact test – Fatigue test – S-N curve – Creep; primary, secondary and tertiary creep – Fracture: Ideal fracture stress – brittle fracture – Griffith’s theory cup and cone type fracture Phase Diagrams: solid solution – intermetallic compound, cooling, curves, non-equilibrium cooling – phase rule – Equilibrium diagrams – isomorphous – eutectic, peritectic and eutectoid reactions with examples – Iron-Iron carbide phase diagram.
