Ni can dissolve high concentrations of alloying elements compared to other metals
Ni can dissolve high concentrations of alloying elements compared to other metals. Alloying elements increase mechanical strength via solid solution or precipitation strengthening. However, the solid solution strengthening effect of Cu is much lower compared to other elements. For example, in recently developed nanocrystalline Ni-Cu alloys both strength and ductility increased with Cu content by only 40% for Cu concentrations increasing by 5 times (from 6 to 32 wt.%). This was associated with gr
