1. Introduce
– A precipitation hardening cast superalloy with a γ’ phase and carbides precipitated in the γ base, resulting in excellent mechanical properties at high temperatures
– Primarily used in the temperature range of 760 to 982°C
– PMET 880
* Rene
– Age hardening Ni-Cr alloy with high strength, high temperature and corrosion resistance
* γ’ precipitates : A₃B type (LI₂) intermetallic compounds
– A : Electronegative elements such as Ni, Co, and Cu
– B : Electronegative elements such as Al, Ti, etc.
– Mo, Ti, Cr : Increased γ’ strength
2. Property
– Excellent thermal fatigue properties, high temperature strength, high temperature corrosion resistance, and thermal stability
