Al Bi Cu (Aluminum Bismuth Copper)
The Al Bi system is characterized by a liquid miscibility gap that closes at 1034 C [Massaslski2] The Al Cu phase diagram [1992Kat, 2009Mir] depicts a number of intermediate phases: CuAl2 (C16 type tetragonal, denoted h) CuAl (g1, orthorhombic) CuAl (g2, monoclinic) Cu5Al4(LT) (f, orthorhombic) e (B81, NiAs type hexagonal) bC/ Cu3Al2 (d, rhombohedral) Cu9Al4(HT) (cC/ Cu9Al4(LT) (c, D83type cubic) and Cu3Al (b, bcc) In the above, HT hightemperature and LT low temperature. The Bi Cu phase diagram is of the simple eutectic type, with little solid solubility between Bi and Cu. Phase diagrams of the above binary systems were also reviewed by [1992Kat]
