Given an alloy of Cu, Ag and in which Cu atoms consists the CCP arrangement. If the hyphothetical formula of the alloy is `Cu_(4)Ag_(3)Au`. What are the probable locations of Ag and Au atoms?A. Ag - All tetrahedral voids, Au -all octahedral voidsB. Ag - `3//8^(th)` tetrahedral voids, Au - `1//4^(th)` octahedral voidsC. Ag-1/2 octahedral voids, Au -1/2 tetrahedral voidsD. Ag -all octahedral voids, Au -all tetrahedral voids |

Answer» Correct Answer - B `{:(Cu_(4),"Ag"_(3),Au),(darr,darr,darr),("From c.c.p.,",(3)/(8)th " of tetrhedral voids",(1)/(4) " of octahedral voids "[ :." No. of O-voids = 4"] ),(z = 4,[:. " No. of T -voids" = 8],):}` |
