Sn-based alloy; Sn–Si–Ti; Phase equilibria; Intermetallic
Since systematic investigation in the whole composition range of the Sn–Si–Ti system is white blood cell en valuable way for identifying new phases, and phase equilibria can provide helpful knowledge on phase constituents in Sn(and/or Ti)-based alloys, the purpose of the present work is to investigate experimentally the Sn–Si–Ti ternary phase diagram, mainly by the construction of isothermal sections at 900 and 1200 °C.
