DYNAMICS OF SPINODAL DECOMPOSITION IN Cu-15Ni-8Sn ALLOY AND THE EFFECT OF NIOBIUM
Cu—15Ni—8Sn合金Spinodal分解动力学及Nb的影响

Using SAXA,TEM techniques and measurement of mechanic properties,spinodal dynamics has been analyzed in Cu-15Ni-8Sn with and without Nb.It has beenfound that dynamic processes in these two alloys agree with LBM theory.Nb increases therate of strengthing and at the same time promotes the growth of celluloid structure occur-red in grain boundaries.Decreases of small angle X-ray strength at early stage of Spinodaldecomposition have been discussed.
