1.Based on the Hume-Rothery Rules, speculate on the possible driving forces behind the tendency for ordering in this system.
2.Speculate on whether you would expect a mixture of AuAg3 to show a greater or lesser tendency toward ordering in this system and explain your rationale (use physical data available in the textbook).
3. Represent the defect chemistry for the introduction of Y2O3 as a solute in a ZrO2 host crystal using Kroger-Vink notation.
4.In the following systems, which would you expect to show complete solid-solution behavior. Justify your answers.
(a) Pt-Ni
(b) Cu-Na
(c) Al-Cr
(d) ZnTe dSe (both compounds crystallize in the zinc-blende fcc structure).
