Calculated liquidus surface. The open dots represent compositions of the five key samples investigated in this work. Dotted lines indicate the vertical sections of Figs. 1 and 2.
The monovariant line L” + (Al)’ + (Al) occurring between 316 and 278 C is depicted in a schematic enlargement of the Bi-rich corner. It almost coincides with the line L”+ (Al)’+ (Zn).
