Textbook Question
Chapter 10, Problem 5RQ
- 4.
A simplified phase diagram for cobalt and nickel is shown. Assuming the lines shown are linear, we can say the mixture has the following characteristics: - ■ Above 1500°C, it is a liquid.
- ■ Below 1500°C, there are two possible phases: face-centered cubic (FCC) phase and hexagonal close-packed (HCP) phase.
Use the workbook provided to determine the phase of a mixture, given the temperature and nickel content.
- a. Write the mathematical equation to describe the dividing line between the HCP region and the FCC region in column C. Reference the nickel content found in column B as needed. Add any absolute reference cells you feel are needed to complete this calculation.
- b. Write the conditional statement to determine the phase in column D. For simplicity, call the phases HCP, FCC, and L. For points on the line, YOU can decide which phase they are included in.
- c. Use conditional formatting to indicate each phase. Provide a color key.
