Stress-Corrosion CrackingCopper and nickel have similar atomic radii and lattice parameters and so the phase diagram is relatively simple (Figure 1)1. At all temperatures, Cu-Ni alloys are represented by a single phase face centered cubic structure. The absence of phase transformation during thermal cycles reduces the effect of welding on mechanica…copper.orgCopper: Rem.
