摘要：A novel cu?6.5ni?1al?1si?0.15Mg?0.15Ce alloy with super-high strength was designed and its corrosion behavior in3.5%NaCl solution at25°C was investigated by the means of SEM observation,TEM observation and XPS *** alloy after solution treatment,80%cold rolling and aging at450°C for1h had the best comprehensive properties with hardness of HV314,electrical conductivity of19.4%IACS,tensile strength of1017MPa,and average annual corrosion rate of0.028mm/*** oxides and chloride products formed at first,followed by the formation of dyroxides *** alloy showed super-high strength,good electrical conductivity and corrosion resistant because ni2si hindered the precipitation of large nial at the grain boundary and the denickelefication of the alloy.
