1900 1863â 1700 1500 1455°C 1300 1345°C (Cr) 1100 (Ni) 700- 590°C Ni,Cr Ni Atomic Percent Chromium Cr Consider a mixture of 80% chromium, Cr, and 20% nickel, Ni, at a temperature of 1 ,300° C. Let's instantly change the temperature to 700°C (as indicated by the arrow on phase diagram), and let the system reach equilibrium. The diagram below shows three microstructures during this process. At the start of the process, only the (Cr) phase is present. At some point during the process, new regions of the (Ni) phase have formed and are growing. At the end of the process, there are two phases present. Identify the phase compositions and direction of diffusion in the following diagram
