Ch. 1. Introduction
Different properties of materials that determine their applicability.
Criteria important to select materials (e.g., cost).
Classification of materials (e.g., metals).
Properties that pertain to a particular class (e.g., metals are strong and opaque,
ceramics are hard and brittle, etc.)
Ch. 2. Atomic Structure and Bonding
How orbitals are filled in atoms and which ones participate in bonding.
Plots of both potential energy and force between atoms: attractive and repulsive parts,
minimum energy, sign of energy and force in different regions.
How to derive the force from the potential energy.
How the depth and shape of the potential well affect materials properties.
Differences between bond types (e.g., ionic, metallic).
Correlation that exists between a class of materials and bonding (e.g., ceramics and
ionic bonds).
Ch. 3. Structure of Crystalline Solids
How to calculate the number of atoms in a volume of material.
Differences between crystalline and amorphous solids, and between single crystals and
polycrystalline materials.
How to distinguish polymorphism and allotropy.
How atoms are arranged in FCC, BCC and HCP crystals and be able to draw the unit cell.
Different properties of FCC, BCC, and HCP crystals (e.g., coordination number, APF):
their values and how they are calculated.
How to calculate the density knowing the crystal structure, lattice parameter, and
atomic weight.
How to identify the crystal structure given the atomic weight, atomic radius, and
density.
Difference in packing order between FCC and HCP structures.
How to identify close packing directions.
Ch. 4. Imperfections in Solids
How vacancies and interstitials are defined.
Which are point (0D), line (1D), surface (2D) and volume (3D) defects.
How properties of a material change near a grain boundary or a surface.
How to calculate number of vacancies at some temperature given the relevant formation
energy.
What happens to the number of vacancies when the temperature is increased or decreased
and why.
What are a solid solution, a solute and a solvent.
What properties of atoms determine the ability to dissolve each other (e.g., similar
atomic radius).
How to calculate weight percent of atoms in a solution given the percent concentrations
and atomic weights.
How to calculate percent concentration of atoms in a solution given the weight percent
and atomic weights.
How the lattice deforms around a vacancy, an interstitial, and dislocations.
How the lattice differs from the bulk properties near a surface or a grain boundary.
Different type of dislocations and be able to draw them.
What is the Burgess vector and what angle it makes to the dislocation line in different
cases.
Ch. 5. Diffusion
What drives diffusion.
Different mechanisms of diffusion.
How and why diffusion increases with temperature and decreases with
activation (diffusion) energy..
Difference between steady state and non-steady state diffusion.
Factors that affect different mechanisms of diffusion .
How to calculate the diffusion flux given the concentration gradient and diffusion
coefficient.
How to calculate the concentration gradient given the diffusion coefficient and
diffusion flux
How to calculate the diffusion coefficient at one temperature from that at
a different temperature or from the diffusion flux and concentration
gradient.
