%X Diffusion reactions of superconducting composite NbTi/Cu, diffusion couple Ti/Cu and Nb/Cu have been studied by means of EPMA. The results indica- te that the initial interface state of the composite NbTi/Cu significantly affect the forming process of intermetallic compounds at the interface, In comparision with the metallurgical binding composite, the intermetallic compounds forms at a higher tem- perature in mechanical binding one. Therefore, the mechanical binding process is beneficial to the production of NbTi/Cu superconducting composite. No intermetallic compounds have been observed in Nb/Cu system. The morphol- ogy of intermetallic phases and the sequence in which they form in Ti/Cu system are somewhat different to that in NbTi/Cu. The relationship between the thickness of compound layer and anealing time obeys the rule of y~(1.5)--t.
