The phase diagram of Aluminium (AI) - Copper $$(Cu)$$ alloy is given above a. (1 mark) At $$500^{?}\mathrm{C}$$, what is the maximum $$\%$$ solubility of Copper (Cu) in Aluminium (AI) in solid state? b. (2 mark) Based on the above diagram, at what temperature and composition the Eutectic point located? c. For alloy of composition $$10\%$$ Copper at $$600^{?}\mathrm{C}$$ 1. ( 1 mark) Describe the solidification regime (at what temperatures the solidification starts and completes), ii. (4 marks) identifying specifically the phase compositions and approximate phase proportions exist at that point.
