The microstructural features and age-hardening behaviors of spray formed Ni-based superalloy have been investigated. The alloy was solutioned at 1140 °C for 8 h followed by ageing at 780 °C for various time in the range of 2 h to 12 h. The microhardness, γ′ precipitates size, morphology, electrical conductivity and positron annihilation lifetime as a function of ageing time were measured. The results...
