主 题:diffusion growth microstructure Nb_3Sn Nb_6Sn_5
摘 要:The diffusion process of Sn in the transformation of Nb_6Sn_5 to Nb_3Sn has been *** experimental results show that the growth of Nb_3Sn laver is controlled by two processes,i.e. the short range diffusion of Sn which is responsihle for the inner layer with large grains,and the long,range diffusion of Sn which results in the outer layer with fine *** was found thai grain size depends on the reaction temperature.A model of Nb_3Sn growth based on the above processes was established and its solution was found to be in good agreement with ex- perimental results.
