Verified step by step guidance1
Identify the composition of the alloy: The problem states that the alloy has a composition of 20% Cu. Since the x-axis of the phase diagram is labeled 'Mole percent nickel', this means the alloy has 80% Ni.
Locate the temperature on the phase diagram: The temperature given is 1300°C. Find this temperature on the y-axis of the phase diagram.
Find the intersection: Draw a vertical line from the 80% Ni mark on the x-axis and a horizontal line from the 1300°C mark on the y-axis. The point where these lines intersect will help determine the phase.
Analyze the phase regions: Observe the phase diagram to see which region the intersection point falls into. The diagram is divided into regions labeled 'Liquid', 'Solid alloy', and possibly others.
Determine the phase: Based on the location of the intersection point within the phase diagram, identify the phase of the alloy at 20% Cu and 1300°C. In this case, the intersection falls within the 'Liquid' region, indicating the alloy is in the liquid phase.
