Microstructural Evolution of a Newly Developed γ' Strengthened Co-base Superalloy
In this work, microstructural evolution of a Co-based superalloy with mainly γ/γ' structure is studied. The nominal composition of the present alloy consists of Ni (27.6), Ti(12.9), Cr(8.7), Mo(0.8), Al(2.6), W(0.2) and Co(47.2 at.%). Ingots was heat-treated at 1100°C for 2 hours (followed by quenching in oil) then at 650°C for 24 hours (air cooling), and finally at 760°C for 16 hours (air cooling). The microstructural investigation was done using TEM and three-dimensional atom probe (3DAP) techniques.
