Please correct answer and don't use hand raiting The phase diagram of a mixture of magnesium and copper shows that two compoundsare formed: MgCu2 that melts at 800°C and Mg2Cu that melts are 580°C. Pure coppermelts at 1085°C and pure magnesium melts at 648°C. There are three eutectics: 9.4%by weight Mg (680°C), 34% by weight Mg (5600), and 65% by weight Mg (380°). (a)Construct the phase diagram showing temperature (y-axis) vs. % by weight Mg (x-axis). (b) Determine the number of degrees of freedom in each area and at each eutecticpoint.
