High temperature tensile strength and stress rupture strength versus time have been measured at temperatures 1400degrees C, 1500, 1600 and 1700 degrees C using alloys PtRh 10%, 20%, 30% and dispersion hardened Pt-DPH. Data collected on Ir at temperatures 1800C, 2000C and 2300C are shown. 10 hour rupture strength data show remarkable loss in creep resistance of PtRh10%, 20% at 1400C while PtLr 20%, 30% and dispersion hardened Pt still maintain creep resistance. At tenperatures above 1600C only Lr withstands creep.
