1. Part I: Define in terms of crystal formation, alignment of the atoms. Then give an example where this might be used in everyday life, or an example of a product formed by this process. In most metals, this process is performed by heating the material (generally until glowing) and then cooling slowly at room temperature. Annealing increases ductility and softens metals (more malleable).

2. Part I: Define in terms of crystal formation, alignment of the atoms. Then give an example where this might be used in everyday life, or an example of a product formed by this process. Cooling slowly creates large crystals.

3. ..is used to increase the strength of malleable metals. Soluble impurities are added to alloys with different temperatures that hardens the metal. Different size crystals give radically different properties.

4. Rapid cooling to reduce crystal size (small crystals formed) and increase hardness.

5. To harden or strengthen by heating and cooling. Tempering usually occurs after hardening metal with a lower temperature to remove some of the hardness.

6. Small crystals outside, larger crystals inside. Produces strong, but flexible steel.

7. Striking a piece of hot metal with a hammer is forging. Using a falling hammer or powered hammer to force metal into a die is dropped forged.

8. Solid solution of metals
