A series of experiments have been designed to investigate the effect of different space positions between liquid Ag-Cu-Sn alloy drop and iron substrates on the liquid/solid interfacial morphologies by a sessile drop method. The results show that Ag-Cu-Sn alloy diffuses into the solid iron substrate, and the amounts are greater and the distances are longer when it diffuses into the lower substrate than that into the upper one. Moreover, there are many primary α-Fe dendrites in the liquid Ag-Cu-Sn alloy close to the upper substrate of liquid bridge or the surface of metal drop. That is due to the effect of gravity.
