Structure of engineering materials I
5 points * 26 lectures, 26 laboratory hours and tutorials * First semester * Clayton * Prerequisites: MTE1510
Crystallography: space lattices, lattice directions and planes; elements of symmetry, crystal systems; stereographic projection; symmetry groups: Atomic packing, structures of metallic, ionic and ceramic crystals. Crystal defects: point, line and planar defects in crystals; energy of formation of a vacancy and interstitial; crystal geometry of dislocations; dislocations in cubic hexagonal crystals; partial dislocations; elastic properties of dislocations; force on a dislocation origin and sources of dislocations; dislocation interactions; Peierls force; structure of stacking faults, twin boundaries and grain boundaries. Diffraction techniques: production and properties of x-rays; kinematic theory of diffraction; intensity of diffracted beams; experimental methods and applications, lattice parameters and crystal structure determination, diffraction from polymers, detection of crystallinity; neutron and electron diffraction.
