Abstract
The rather surprising position of the Kirkendall pores in Nb3Sn superconductor grown by bronze technique is clarified. It is shown that Sn is the fastest diffusing species, which seems to be unusual considering the crystal structure of Nb3Sn. Further, we explain the dramatic change in the growth rate and the activation energy for growth of the product phase, when the Sn composition in the Cu(Sn) bronze alloy is changed from 7 to 8 at. %. A. Paul would like to acknowledge the financial support received from Department of Science and Technology, Government of India (Grant No. SR/FTP/ETA-18/2006) for this research work. REFERENC
