Phase diagram • Phase diagram is a graphical representation of all the equilibrium phases as a function of temperature, pressure, and composition. • For one component systems, the equilibrium state of the system is defined by two independent parameters (P and T), (T and V), or (P and V). Pressure-temperature phase diagram for H 2 O: The copper - zinc phase diagram is a bit simpler than the copper - tin phase diagram but still complex enough. There are all kinds of brass' but typically we are at the copper-rich side. Of course, if we want to look at all copper alloys, we would need a bunch of more binary phase diagrams, in particular for the elements arsenic (As), antimony, (Sb), silver (Ag), and lead (Pb) since these are ...
