| Abstract Scope |
Latest developments of nickel-based single crystals superalloys mainly focus on adjusting Re and Ru additions in order to achieve high creep properties at high temperature and a stable microstructure (e.g: CMSX, and TMS alloys series). Following a different strategy, TROPEA has been developed introducing Pt element as a strengthening element for high temperature aircraft engines components. TROPEA exhibits excellent tensile properties (Yield Stress > 2nd or 3rd SX superalloys and ~ 2nd SX superalloys respectively below and above 800°C) and combines high fatigue properties (LCF and VHCF particularly at low temperature) and high creep resistance at temperatures above 1200 °C. These properties make TROPEA a promising SX superalloy for super cooled turbine blade. Otherwise, platinum additions have shown to significantly stabilize gamma prime phase near solvus temperature outlining the potential to design new platinum containing alloys in addition of or as an alternative to rhenium. |
