%X Diffusion reaction of superconductig composite NbTi/Cu assembled both mechanicallyand metallurgically,diffusion couples Ti/Cu and Nb/Cu have/been studied by means ofEPMA.The results indicate that the initial interface state of thecomposite NbTi/Cu significantly affects the forming process of intermetallic compounds atthe interface.In comparison with the metallurgically bound composite,the intermetallic com-pounds forms at a higher temperature in mechanically bound one.Therefore.the mechanicalhinding process is beneficial to the production of NbTi/Cu superconducting composite.No intermetallic compounds have been observed in Nb/Cu system.The morphology ofintermetallic phases and the sequence in which they form in Ti/Cu system are somewhatdifferent from that in NbTi/Cu.The relationship between the thickness of compound layerand annealing time obeys the rule of y~(1.5) ∝ t.
