Abstract

The effects of different Al contents (0, 1, 3, and 5 wt%) on the mechanical properties and corrosion behavior of Cu–10Ni-x Al alloy were studied by tensile test, immersion test and electrochemical test. The results demonstrate that a certain Al addition can effectively enhance the mechanical properties of the Cu–10Ni alloy without sacrificing corrosion resistance. That is, Cu–10Ni-1 Al alloy exhibits the best comprehensive properties after thermo-mechanical treatment. The tensile strength is 658 MPa, the elongation is 15.45%, and the corrosion rate is 0.03775 mm/y. Electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM) results show that the Ni₃Al phase precipitated during the aging process inhibits the recrystallization behavior of the alloy. Therefore, the strength of Cu–10Ni alloy increases as increase Al content, due to solid solution strengthening, deformation strengthening, and precipitation strengthening. However, the formation of micro-galvanic corrosion between the Ni₃Al precipitates and the matrix reduces the corrosion resistance of the alloy.
