Abstract
A high temperature article, for example a rocket nozzle suitable for liquid-fuelled rocket motors for satellites, is formed from an alloy which is a binary or tertiary alloy from the Pt-Ir-Rh system. Such alloys exhibit a good balance between ease and reliability of manufacture, cost of alloy and high temperature strength and oxidation resistance.
Claims3
A rocket nozzle consisting essentially of a binary alloy of from 0.5 to 10 wt % rhodium and the remainder being iridium, said alloy being characterized by its ability to withstand the combination of high temperatures in excess of 1150.degree. C. and structural loads.
