2.9 Describe FCC, BCC, and HCP lattice structures. 2.10 Two hypothetical metals are created with different elements that have the same atomic mass (g/mole) and the same atomic radius. Metal A has a density of 9.50 g/cm3 and metal B has a density of 8.73 g/cm3. If one of these metals has a BCC lattice structure and the other has an FCC lattice structure, identify the structure that corresponds to each of one of them. Justify your answer. 2.12 Referring...

The atomic radius of FCC aluminum is 0.142 nm. What is the lattice parameter of the unit cell? What is the most densely packed direction and plane in this material? If this was an BCC material, on the cube shown below sketch the most densely packed crystal plane, and state that plane here. Identify the plane shown below for a cubic system and compute the planner density for a BCC material of the plane shown.

What is the major disadvantage of the HCP structure (as compared to the BCC or FCC structure)? Which crystal lattice structure has the tendency to be a very good ductile material? Which crystal lattice structure has the tendency to be a brittle material? If you were to create an alloy with the BCC structure with an element (which has an atomic radius much smaller than the atoms in the crystal structure), what would be the type of defect that will...
Atomic densities and atomic volumes Problem 3. In this problem, we will calculate the atomic density ) and atomic volume () of two different pure metallic solids, Iron (Fe) and aluminum (AI). We will compare and contrast two different calculation methods flabeled Method I and Method II below. We will exploit the technique of "DIMENSIONAL ANALYSIS in our calculations. Method I. Calculate p and n based on knowledge of the mass density of the solid (the symbol for mass density...
