3. Draw the following planes in a simple cubic unit cell: (213Ì…), (312), (122Ì…) 4. Draw the following planes in an HCP unit cell: (101Ì…1), (2Ì…200), (01Ì…10) 5. An x-ray diffractometer chart for an element (either BCC or FCC crystal structure) showed diffraction peaks at the following 2ð œƒ angles (degrees): 38.184, 44.392, 64.576 and 72.547. a. Determine the crystal structure. b. Calculate the lattice constant, ð ‘Ž. c. Identify the element. 6. A brass consists of 80 wt.% Cu and 20 wt.% Zn. What are the atomic percentages of Cu and Zn in this alloy?
