please show the process, explain in detail. This is a long question thanks!

10.7 Given here are the solidus and liquidus tempera-tures for the copper—gold system. Construct the Aphase diagram for this system and label each region. 5"" ' °f 1 Plot the phase diagram at copper-gold system.

Based on your result in part a, what is the composition of the alloy that meltscongruently? What is the melting temperature for this composition? Calculate the degree of freedom for the condition in part b assuming fixedpressure. (1. Calculate the degree of freedom for each region you have label in part a assumingfixed pressure. Based on the phase diagram you have drawn in part a, cite the phase(s) presentand calculate/estimate the composition and the relative amounts (in terms of massfractions) of the phase(s) for an overall composition of 40 wt% Au at each of thefollowing temperatures: 900°C, 980°C, and 1050°C. f. For a Cu-Au alloy of composition 40 wt% Au, draw the schematics of themicrostructures that would arise from equilibrium and non-equilibrium cooling.Estimate compositions if any part of the microstructure has composition differentthan the overall composition of 40 wt% Au based on the phase diagram you havedrawn.
