An investigation of the high-Al part of the Al-Pd-Ru phase diagram at 790 to 900°C
Partial isothermal sections of the Al-Pd-Ru phase diagram at 790 and 900 degrees C are presented. Complex orthorhombic 8-phases extending from Al3Pd up to 15 at.% Ru exhibit structural variants including transient irregular structures. The Al3Pd2 phase dissolves up to 2 at.% Ru, Al13Ru4 <2.5 at.%...

Partial isothermal sections of the Al-Pd-Ru phase diagram at 790 and 900 degrees C are presented. Complex orthorhombic 8-phases extending from Al3Pd up to 15 at.% Ru exhibit structural variants including transient irregular structures. The Al3Pd2 phase dissolves up to 2 at.% Ru, Al13Ru4 <2.5 at.% Pd and Al2Ru up to 1 at.% Pd. A stable icosahedral quasicrystalline phase is formed around the Al71.5Pd17Ru12.5 composition. At nearby compositions two complex primitive cubic phases with a approximate to 2.0 and approximate to 4.0 nm were observed. These cubic phases exhibit powder X-ray diffraction (XRD) patterns very similar to that of the icosahedral phase. At compositions close to the high-Ru limit of the epsilon-range the electron diffraction patterns of complex orthorhombic structures and ID quasicrystalline structure were revealed. At lower-Al concentrations three ternary cubic phases structurally related to quasicrystals are formed: primitive C (a approximate to 0.75 nm), bcc C-1 and fcc C-2 with a double lattice parameter.
