用凝胶辊(J-R)法和热扩散法制备了18芯Nb-Al薄带。在750℃~1000℃等温热处理条件下，研究了烧结温度和时间对Nb-Al二元系的扩散程度和超导性能的影响。结果表明，低温扩散法可获得J-R型Nb3Al超导相，在800℃~900℃之间烧结可获得较高的临界温度(T_C)。磁性分析表明，低温扩散法在900℃下烧结24 h得到的J-R Nb3Al样品的最佳T_c约为15.1K。
Eighteen-core Nb-Al strands have been fabricated by the jelly-roll (J-R) method followed by the thermal diffusion method. The effects of sintering temperature and time on the extent of diffusion and the superconducting properties of the binary Nb-Al system were investigated, with thermal diffusion taking place under isothermal heat treatment at 750 °C-1000 °C. Results showed that the J-R Nb3Al superconducting phase could be obtained by the low-temperature diffusion method, and a higher critical temperature (Tc) was obtained with sintering between 800 °C and 900 °C. On optimizing the sintering temperature and time, it was indicated that the sintering temperature had more significant effects on the superconducting properties than the sintering time. The magnetic analysis showed that the J-R Nb3Al samples were obtained with an optimal Tc of about 15.1 K by the low-temperature diffusion method with sintering for 24 h under 900 °C.
