Investigation of the Al–Cu–Rh phase diagram in the vicinity of the decagonal phase

An investigation of the Al–Pd–Rh phase diagram between 50 and 100at% Al

“…The present work continues the long-term study of the alloy phase diagrams of aluminum with platinum metals ( [1][2][3][4][5][6][7][8][9][10] and references therein). The interest in these alloy systems is due to the formation there of complex periodic and quasiperiodic intermetallics attractive for both basic and applied research.…”

“…In ternary alloy systems, they can dissolve significant quantities of a third element (Mn, Fe, Co, Ni, Cu, Re), which results in the formation of wide-ranging solid solutions with various regular structures and intermediate states [2][3][4][5][8][9][10]12]. This is also expected in Al-Pd-Rh.…”

“…[3,4] apart from the Al-Rh orthorhombic phases designated O 1 and O 2 in Ref. [3]. The O 1 -phase is renamed 3 16 and the O 2 -phase 3 6 according to the nomenclature of Ref.…”

An investigation of the Al–Ni–Rh phase diagram between 50 and 100at% Al

“…The phase designated in Ref. [1] as O 1 -phase is renamed 3 16 and the O 2 -phase is renamed 3 6 since they are structurally related to the more extensively studied AlePd 3-phases. These complicated phases belong to the so-called 3-family 1 exhibiting the same lattice parameters in two principal directions and various lattice parameters in the third.…”

“…Following the investigation of the AleCueRh [1] and AlePdeRh [2] constitutional diagrams, in this contribution we present the results concerning AleNieRh. In their high-Al regions these alloy systems exhibit the formation of complex periodic and quasiperiodic intermetallics attractive for both basic and applied research.…”
