The Crystal Structure of Ru4Al13.

Development of a database for the prediction of phases in Pt–Al–Cr–Ru alloys for high-temperature and corrosive environments: Al–Cr–Ru

“…The composition ranges of the Ru 4 Al 13 and RuAl 2 phases are satisfactory, as both have been reported as having a composition range from stoichiometric to having a 5 at. % composition range [38,40,51]. The results for the SL and MSL descriptions of the B2 phase compare well.…”

The Structure of an Al-Ni-Ru Monoclinic Phase Al<SUB>13</SUB>(Ru,Ni)<SUB>4</SUB>

“…13) For the ordinary X-ray diffraction analysis, least-squares software of SHELXL-97 14) was used together with the neutral atomic scattering factors and values of dispersion corrections provided by International Tables for X-ray Crystallography Volume C. 15) The cell parameters of each sample and experimental details for the measurements of Mo-K radiation were summarized in Tables 2-4 together with the final results. It may be added that the structure of the Al-Ru binary monoclinic phase 16) was also refined in the present study. Since the Al 76:5 Ru 23:5 ingot prepared by the arc melting is mainly composed of monoclinic phase, a single crystal sample of the binary monoclinic phase was selected from an as-melted ingot without further high temperature annealing.…”

Derivation of the liquidus surface projection for the Al–Pt–Ru system from as-cast samples

“…Schwomma et al [19] identified RuAl 2 and RuAl. Edshammar [20][21][22] investigated Ru 4 Al 13 , RuAl, Ru 2 Al 3 , RuAl 2 and a phase only observed in arc-melted samples, RuAl ∼2. 5 .…”
