Abstract
The preliminary liquidus projection of the ternary Sn-Co-Ni system is determined. No ternary compound is found. There are eight primary solidification phases: Sn, CoSn 3 , CoSn 2 , CoSn, (Ni,Co) 3 Sn 2 , (Ni,Co), Ni 3 Sn and Ni 3 Sn 4 . More experimental measurements of the primary solidification phases and thermal analysis are needed. © 2012 IEEE.
