rphous Binary Phase Diagrams Microstructure Part A Equilibrium microstructures The phase diagram in Figure 1 shows the cooling process for a copper-nickel mixture with 60 wt% nickel. Several schematic representations of microstructures are provided, L is the liquid phase and α is the solid phase. Identify the microstructure at each point shown on the cooling line and place the corresponding image in the boxes below. Assume that the mixture cools slowly. Learning Goal To identify the changes in the microstructure of a binary isomorphous mixture and determine the relative compositions of the phases as the mixture cools. Drag-and-drop the appropriate labels to their respective targets. Hints A binary phase diagram describes the phases for a mixture of two different components. In a binary somorphous phase diagram, the two components are completely soluble. The equilibrium state of a mixture with a known temperature and overal composition is described by a single point on the phase diagram. When a mixture cools and changes from the liquid phase to the solid phase, a specific type of microstructure forms that can influence the materials macroscopic properties significantly. For a sufficiently slow cooling process, the Figure 1 #lof! at point A at point B at point at point F 1600 1500 1453 1400 1300 1200 Reset Help 1100 1085 C Submit My Answers Give Up 1000 100 Ni Cu Composition (wt%Ni)
