Question

A. In the Cu-Ni phase diagram above, use Gibbs phase rule to determine the number of degrees of free

dom at each of the four Xs.

B. In the same phase diagram above a dashed line signifies a 50/50 wt% Cu-Ni alloy. Draw a representative schematic of the phases present for each of the following tem. the Cu-Ni phase diagram above, use Gibbs phase rule to determine the number of degrees of freedom at each of the four Xs.
in graph we have
in x-axis composition(ni)(0-100)
in y-axis temperature in centigrade(1000-1600)
composition at top of graph at %ni(0-100)
composition at right side of graph is temperature in faranheit(2000-2800)
in graph from center line(alpha+L) between 40 and 60
in graph straight line from 1085 degrees(temp.C)-1453 degrees(temp.F)
in graph liquid at left side of (alpha +L)
solid line at right side of (alpha +L).
