Question
Following three planes (P1, P2, P3) in an fc unit cell are shown in the figure below. Consider the following statements and choose the correct option/options that follow:
Options
A.P1 contains no three dimensional voids.
B.P2 contains only octahedral voids.
C.P3 contains both octahedral and tetrahedral voids.
D.All of these
Solution
A. P1 represent one of the close-packed layer having triangular voids only.
B. P2 contains location of OVs (edge centers of unit cell).
C. P3 contains 3 OVs locations (one at body center and two at edge center). Also, plane
P3 contains the body diagonals,hence it contains TVs location(TVs lie at body diagonal)
