Not obvious in these plots but evident in the copper-nickel phase diagram is a tendency to immiscibility in the fcc phase at low temperatures. This contributes to a further transformation at 750 K, in which the amount of copper combined with sulphur as digenite sharply declines, whereas that of nickel and iron combined with sulphur in ... the tie-line intersection with the β + L−β phase boundary occurs at 97.5 wt% Sn, which is the composition of the β phase.

The age-hardenable copper-nickel-silicon alloys with 1.0 to 4.5% Ni and 0.2 to 0.6% Be are not dealt with here. In European standards, these alloys are assigned to ‘low-alloyed copper alloys’ (see R 13388 and relevant product standards). Figure 1. (DKI A 4049) Cu-Ni equilibrium diagram the thermal equilibrium diagram for the alloy of Copper and Nickel. In order to find what temperature 60% copper solidifies at we simply draw a vertical line from 60% copper until it hits the solidus line and at this is the point where 60% Copper has fully solidified. 0 100 10 90 20 80 30 70 40 60 50 50 60 40 70 30 80 20 90 10 100 0 900 1000 ...

Cu-Ni EXAMPLE

In 1751, A.F. Cronstedt succeeded in isolating nickel. However, Cu-Ni alloys were in existence much earlier, mostly prepared by processing ores. Today, Cu-Ni alloys have gained a variety of interesting applications because of their specific characteristics . Copper and nickel are adjacent to one another in the periodic system of elements, with atomic numbers 29 and 28 and atomic weights 63.54 and 68.71.The two elements are closely related and are completely miscible in both the liquid and solid state. Cu-Ni alloys crystallise over the whole concentration range in a face-centred cubic lattice. The lattice spacing of the face-centre cubic solid solution varies almost linearly with atomic concentration between the values for copper (3.6153 . 10-8cm) and that for nickel (3.5238 . 10-8cm). Cu-Ni alloys are alloys of copper (base metal with the largest individual content) and nickel with or without other elements, whereby the zinc content may not be more than 1%. When other elements are p...

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 ...
