Q2
44. Given an alloy of Cu,At and Au in which Cu atoms constitiute the ccp arrangement. If the hypothetical formula of the alloy is Cu4Ag3Au, the probable locations of Ag and Au atoms are (1) Ag- all tetrahedral voids ; Au- all octahedral voids (2) Ag- 3/8 th of tetrahedral voids ; Au- 1/4 th of octahedral voids (3) Ag- 1/2 of octahedral voids ; Au- 1/2 of tetrahedral voids (4) Au- all tetrahedral voids ; Ag- all octahedral voids
