Abstract
The creep behaviour of several ternary Pt–Al–Z alloys (Z=Cr, Ru and Ir) at 1300 °C was investigated by conducting stress–rupture tests. The ternary elements were selected either to stabilise the L1 2 form of Pt 3Al, or as solid–solution strengthening elements for the Pt matrix. The effects of ternary alloying elements on the high-temperature mechanical behaviour of Pt-based (Pt)/Pt 3Al alloys are critical. The ferritic ODS alloy PM2000 was used as a benchmark. The tested samples were examined using scanning electron microscopy. The results are very promising, particularly those for the Pt 86:Al 10:Cr 4 alloy, which showed very good stress–rupture strength. The Pt–Al–Z alloys had lower strength than PM2000, but far superior ductility.
