Abstract:By measurement of mechanical and electrical properties, modulation wavelength, TEM techniques etc.,the effect of Y on the spinodal decomposition in a Cu-9Ni-6Sn alloy has been studied. The results show that Y can accelerate spinodal decomposition,。the alloy, hinder the growth。;celluoid sLructurers occurring at grain boundaries, and improve the combination of strength and plasticity:
