Study Notes
Solid Solutions
- Copper and nickel atoms can form a solid solution, where nickel acts as a solute dissolved in copper, the solvent.
- In this specific configuration, nickel atoms replace copper atoms in the face-centered cubic (fcc) crystal structure.
- This is classified as a substitutional solid solution, as one atom type replaces another in the crystal lattice.
- This solid solution is possible because the copper and nickel atoms have similar sizes.
- The Hume-Rothery rules dictate that for complete miscibility in metallic solid solutions, the metals need to be very similar in characteristics.
- This is exemplified by the water-alcohol system, where both liquids are completely soluble in each other in all proportions.
