Experimental determination of phase diagram in the Zn-Fe binary system ... A phase diagram of the Zn-Fe binary system was determined by two-phase alloys. • Solubility ranges of IMC phases were confirmed to shift to Fe-rich side. • A first-order order (δ 1k ) + disorder (δ 1p) miscibility gap was found out. • Solubility of Fe in the liquid Zn at 450 °C was over twenty times larger than that in the literature. • Cu-Fe-Zn (Copper-Iron-Zinc) | SpringerLink There are no intermediate phases in the Cu-Fe system. The phase diagram was recalculated by [] for both stable and metastable equilibria.The Cu-Zn phase diagram [Massalski2] is characterized by a series of peritectic reactions, which yield CuZn (β, bcc), Cu 5 Zn 8 (γ, D8 2-type cubic), CuZn 3 (δ, hexagonal?), and CuZn 4 (ɛ, cph). The bcc phase β orders to a B2 structure around 460 °C.
