Figure 3, shows the isomorphous phase diagram for nickel and chromium, which are the main elements of the super alloy. During the casting process, nickel and chromium are melted at given temperature to create a well annealed initial batch. Figure 3: Isomorphous Phase Diagram Ni-Cr. 5. Complete the values missing on the graph. 6. Discuss what are the factors on that allow to fix the percentage of chromium needed in this alloy. In order the produce the IN718 alloy, we need a percentage of chromium between 15% and 40%. While increasing the temperature of the furnace above 1000C costs 8000(exp(100T)exp(1005))+1000DHs/h where T is the increase of temperature. The price of Nickel is 300DHs/kg and for Chromium is 14000DHs/kg. 7. Design a casting process for the 20% chromium nickel alloy, to produce 100kg/h. The percentage of molybdenum in the final product is 3%. We achieve this by diffusing the molybdenum atoms into the initial batch. 8. Propose a simplified diffusion model, to estimate the concentration of molybdenum and time needed to reach the target concentration at a depth of 10cm. (chose representative values for any data needed)
