4. A composite of Aluminum and Nickel is composed4. A composite of Aluminum and Nickel is composed of 50 wt. % Ni. The phase diagram of Al and Ni is shown below. Find the following at 500 °C (2.5 point) a) What phase or phases we have at 50 wt. % Ni. b) If your answer to part (a) is one phase, what is the amount and composition of that phase. If your answer to part (a) consists of two phases, determine the amount of each phase and the composition of each phase. (you should show step by step your solution.) you can draw lines on the diagram to show me the composition and temperature.
