If components in an alloy are not uniformly distributed, why will it not be treated as an ideal solid solution?
Answer and explanation
Correct answer: Because a solid solution must also be homogeneous
A solid solution is still a solution, so it must have a sufficiently uniform composition throughout the solid phase. If the alloy components are unevenly distributed, different regions have different compositions and the material behaves as a heterogeneous mixture or multiphase material. Alloys can contain solid solutes, and metals are not gases, so the other explanations are false.
