The phase diagram of Aluminium (Al) - Copper (Cu) alloy is given above a. (1 mark) At $$500^{?}\mathrm{C}$$, what is the maximum $$\%$$ solubility of Copper $$(\mathrm{Cu})$$ 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 $$600^{?}\mathrm{C}$$ i. (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.
