| Popis: | The platinum-rich region of the Pt-Al-Ru system was investigated with a view to stabilizing the displacive (martensite-type) transformation in Pt3Al. In the alloys with low ruthenium contents, ruthenium was found to be partitioned almost exclusively to the fcc Pt phase with extremely limited solubility in Pt3Al. The low-temperature D0′C form of Pt3Al was found to co-exist with the Pt phase. At high Ru additions (greater than 20 at.%), a two-phase mixture of an hcp Ru solid solution and the high-temperature L12 form of Pt3Al was observed. No ternary phases were observed in any of the alloys studied. |
