The Al-Zr phase diagram [Massalski2] depicts the following intermediate phases: Al3Zr (D023-type tetragonal), Al2Zr (C14, MgZn2-type hexagonal), Al3Zr2 (Al3Zr2-type orthorhombic), AlZr (Bf, CrB-type orthorhombic), Al4Zr5 (Ga4Ti5-type hexagonal), Al3Zr4 (Al3Ir4-type hexagonal), Al2Zr3 (Al2Zr3-type tetragonal), Al3Zr5 (D8m; W5Si3-type tetragonal), AlZr2 (B82; Ni2In-type hexagonal), and AlZr3 (L12; AuCu3-type cubic). There are no intermediate phases in the La-Zr system and the mutual solubility between La and Zr is negligible. (...truncated)
