Abstract
Abstract The Al–Pd–Fe alloy system exhibits a continuous range between the solid solution of b.c.c. Fe extending at 1000 °C up to 53 at.% Al and congruent AlPd. At higher Al concentrations three ternary cubic phases designated C, C 1 and C 2 and orthorhombic O–Al 13 (Fe,Pd) 4 were revealed. The Al–Pd orthorhombic e -phases dissolve up to ∼10 at.% Fe and exhibit e 16 and e 22 structural variants in addition to e 6 and e 28 typical of binary compositions. Al 13 Fe 4 dissolves 5 Fe 2 up to 3.9 at.% Pd, Al 2 Fe up to 1.4 at.% Pd, Al 3 Pd 2 up to 1.1 at.% Fe. Partial isothermal sections are presented for 1020, 995, 975 and 900 °C.
