## Phase Change in a Nickel-Copper AlloyA 30 wt% Ni-70 wt% Cu alloy is gradually cooled from 1400°C (2550°F) to 1150°C (2100°F).### Questions**(a)** At what temperature does the first solid phase form? (Input your answer in °C)**(b)** What is the composition of this solid phase? (Input your answer in %wt Ni)**(c)** At what temperature does the last of the liquid solidify? (Input your answer in °C)**(d)** What is the composition of this last remaining liquid phase? (Input your answer in %wt Ni)### Explanation- **Illustration**: The exercise is based on theoretical data which might be derived from phase diagrams, specifically addressing when certain phase transformations occur as temperature changes.- **Focus Points**: Determining phase formation temperatures and compositions is crucial for understanding alloy behaviors and properties during cooling processes. ### Cu-Ni Phase DiagramThis phase diagram illustrates the phase behavior of a copper-nickel (Cu-Ni) alloy as a function of temperature and composition.#### Axes:- The x-axis represents the composition of nickel in the alloy, displaying two scales: - Atomic percent (at% Ni) from 0 to 100. - Weight percent (wt% Ni) from 0 to 100.- The left y-axis shows the temperature in degrees Celsius (°C) ranging from 1000°C to 1600°C.- The right y-axis shows the temperature in degrees Fahrenheit (°F) ranging from 2000°F to 2800°F.#### Key Lines:- **Liquidus Line**: Marks the boundary above which the alloy is entirely liquid.- **Solidus Line**: Marks the boundary below which the alloy is entirely solid.- The region between these lines represents a phase where both solid and liquid phases coexist, denoted as α + L.#### Phases:- **Liquid Phase**: Found above the liquidus line.- **Solid Phase (α)**: Found below the solidus line.- **Two-Phase Region (α + L)**: Exists between the liquidus and solidus lines.#### Notable Points:- **Point A**: Located in the solid phase region.- **Point B**: Located in the two-phase region (α + L), showing the presence of both solid and liquid phases.#### Temperature:- The maximum labeled temperature is 1453°C at the 100% Ni point on the phase diagram.#### Composition and Temperature Labels:- Near the top right corner, there is a yellow box for providing specific composition and temperature values, currently left blank for customization.This diagram is crucial for understanding the melting and solidification behaviors of Cu-Ni alloys, which is vital for applications requiring controlled alloying and thermal properties.
