6. The phase diagram for magnesium-copper at constant pressure shows that two compounds are formed: MgCu2, which melts at 800°C, and Mg Cu, which melts at 580°C. Copper melts at 1085°C, and magnesium at 648°C. The three eutectics are 9.4% by weight Mg (680°C), 33.4% by weight Mg (580°C) and 65% by weight Mg (380°C). Construct the phase diagram. State the variance for each area and eutectic points.

6. The phase diagram for magnesium-copper at constant pressure shows that two
compounds are formed: MgCu2, which melts at 800°C, and Mg2Cu, which melts at
580°C. Copper melts at 1085°C, and magnesium at 648°C. The three eutectics are 9.4%
by weight Mg (680°C), 33.4% by weight Mg (580°C) and 65% by weight Mg (380°C).
Construct the phase diagram. State the variance for each area and eutectic points.
