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

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

“…Early experimental studies suggested that a thermodynamic database for the development of Pt-alloys for high-temperature applications should be based on Pt-Al-Cr-Ru [7,13]. Experimental studies of the four ternary systems have been undertaken by [14][15][16][17] (Al-Cr-Ru), [18][19][20] (Pt-Cr-Ru), [21,22] (Pt-Al-Ru), and [23][24][25] (Pt-Al-Cr). Studies of as-cast alloys were performed in order to determine the solidification reactions and liquidus surface projections.…”

“…A thermodynamic model for the Pt-Al-Ru ternary system was completed by Prins et al [21,26], its optimisation based on experimental work by Prins et al [21,22]. The Cr-Pt-Ru system had been modelled earlier by Glatzel and Prins [27], but more phase equilibrium data has become available [18,19] since the initial assessment that has led to a more accurate optimisation [28].…”

Investigation of as-cast alloys in the Pt–Cr–Ru system

“…The information required to undertake the computer assessments is either gleaned from literature, or when not available, undertaken within the project. Experimental work has already been completed on Al-Cr-Ru [5][6][7], Pt-Al-Ru [8,9] and Pt-Cr-Ru [10][11][12], while work is being done on the Pt-Al-Cr system [13]. wide composition range from ∼34 to ∼85 at.% Pt.…”

Formation of Complex Intermetallics in the Al-Rich Part of Al-Pt-Ru

“…In [2] it was only investigated below 30 at.% Al with a view to stabilizing the displacive transformation in AlPt 3 . More recently, [3] the liquidus surface projection for the Al-Pt-Ru ternary system was estimated in the whole compositional region based on the microstructural characterization of 16 arc-melted alloys. An incomplete solidus projection was also deduced in Ref 3, some items of which are not compatible with equilibrium.…”
