A contribution to the Al-Pd-Cr phase diagram
A contribution to the Al-Pd-Cr phase diagram
The Al-Pd-Cr alloy system was investigated in the compositional range above 50 at.% Al. The binary Al-Cr phases theta, eta, mu, nu and gamma(2) extend up to about 1, 2, 1, 1 and 3 at.% Pd, respectively. The binary Al-Pd epsilon, delta and beta-phases dissolve up to 3, 4 and at least 10 at.% Cr, resp...

The Al-Pd-Cr alloy system was investigated in the compositional range above 50 at.% Al. The binary Al-Cr phases theta, eta, mu, nu and gamma(2) extend up to about 1, 2, 1, 1 and 3 at.% Pd, respectively. The binary Al-Pd epsilon, delta and beta-phases dissolve up to 3, 4 and at least 10 at.% Cr, respectively. Five ternary structures were revealed in a quite small compositional range adjusting to that of the Al-Cr p.-phase. One, resembling the high-temperature Al3Mn phase (T-phase, orth. a = 1.47, b = 1.24 and c = 1.25 nm), is formed in a small region around Al77Pd7Cr16 composition. A hexagonal structure with a=1.77 and c = 1.25 nm resembling Al-Ni(Cu)-Cr zeta-phase was revealed around Al81.5Pd1.5Cr17 and another hexagonal structure with very close lattice parameters around Al73Pd11Cr16. A ternary epsilon-phase resembling that in Al-Ni-Cr (orth., a = 1.24, b = 3.46 and c = 2.04 nm) was found at 970 degrees C around the Al77.5Pd1.5Cr21 composition. An additional orthorhombic phase with a=2.48, b=3.87 and c = 2.04 nm was found to be formed between about Al80Pd4Cr16, Al73Pd8Cr19, Al77Pd4Cr19 and Al77Pd6Cr17. Partial 930, 970, 990 and 1020 degrees C isothermal sections are presented. (C) 2010 Elsevier B.V. All rights reserved. |
