Investigation of the Al-Pd-Fe phase diagram between 50 and 100 at.% Al: ternary phases

The ternary Al-Pd-Fe intermetallic phases formed in the range of 50 to 100 at.% Al were studied by scanning and transmission electron microscopy and powder X-ray diffractometry. The refined lattice parameters of the orthorhombic O-Al-13(Fe,Pd)(4) phase (Cmcb) are a 1.5499(4) b = 0.8102(5) and c = 2.3848(4) nm, of the cubic C (Pm (3) over bar) phase a = 0.7655(9) nm, of the cubic C-1(Im (3) over bar) phase a 1.5354(3) nm and of the cubic C-2 (Fm (3) over bar) phase a = 1.5510(1) nm.
