3. Metаl crystаl structures cоnsist оf lаttice patterns that can be brоken down to the smallest repetitive volume, known as a unit cell. We have discussed three types of cubic structures, simple cubic (SC), body centered cubic (BCC), and face centered cubic (FCC) structures. Answer the following questions below: A. (0.5pts) Sketch a SC structure AND a FCC structure B. (1pts) Calculate the number of atoms per cell AND atomic packing factor for SC AND FCC (MUST state/illustrate how to determine parameters for both structures – show work/thought process). C. (0.5pts) For a metal that consists of a FCC structure, describe one plane in detail that is susceptible to slip/deformation. Responses can include sketches if it helps convey your thought process – responses that include a sketch must explain the main concept of why this plane is susceptible to slip/deformation.
