The effect of the size of NbTi filaments on interfacial reactions and the properties of InSn-based superconducting solder joints

Abstract:

Interactions of superconducting Nb(47 wt% Ti) with liquid binary In-35 wt% Sn and Bi-containing ternary (In, 15 wt% Bi)-35 wt% Sn solders have been examined for the first time up to 450 °C. Reaction of NbTi with InSn results in an intermetallic phase, (Nb,Ti)Sn2, the morphology and chemical composition of which depends on the size of NbTi filaments. Larger filaments react to form a thin uniform (Nb,Ti)Sn2 phase with a Nb:Ti ratio of 6:1, while for finer filaments large (Nb,Ti)Sn2 grains grow ...
