Abstract

Nb3Sn is intermetallic compounds being used as superconductor formed by diffusion of Sn through grain boundary during internal tin process. It was known that grain boundary diffusion is dominant among any other mechanism. Numerical approached by finite difference method is used to study the distribution concentration of Sn. The present study focused on duplex heat treatment process i.e. it consists of two step heat treatments. Temperature and time of heat treatments were varied between 675-800oC and 32-200 hours, respectively. Duplex heat treatment can increase the Nb3Sn layer thickness, with the optimum increase was obtained as the first heat treatment temperature was set to be lower than that of the second one. The growth of the Nb3Sn at the Nb3Sn-Nb boundary depends largely on the concentration Sn at the grain boundaries.
