EFFECT OF Y ON THE SPINODAL DECOMPOSITION RATE AND MECHANICAL PROPERTIES OF Cu-9Ni-bSn ALLOY
（Kunming Institute of Precious Metals, Kunming 650221, China）
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:
Key words: Cu-9Ni-6Sn spinodal decomposition Y
