Question
Given an alloy of Cu, Ag and Au in which Cu atoms constitute the CCP arrangement.If the hypothetical formula of the alloy is Cu4Ag3Au. What are the probable locations of Ag and Au atoms.
Options
A.Ag - all Tetrahedral voids; Au - all Octahedral voids
B.Ag - 3/8th Tetrahedral voids; Au - 1/4th Octahedral voids
C.Ag - 1/2 Octahedral voids; Au - 1/2 Tetrahedral voids
D.Ag - 1/2 Octahedral voids; Au - 1/2 Tetrahedral voids
Solution
Cu4 → Froms c.c.p. z = 4
Ag3 →
th of tetrahedral voids, [∴ No. of T- voids = 8].
Au →
of Octahedral voids [∴ No. of O - voids = 4]
Ag3 →
th of tetrahedral voids, [∴ No. of T- voids = 8]. Au →
of Octahedral voids [∴ No. of O - voids = 4]Create a free account to view solution
