Abstract
The stability of a Co-based alloy designed to possess a microstructure comprising of L1, γ′ CoTi-type precipitates embedded in an A1, γ Co solid solution matrix has been investigated. The alloy showed acute microstructural instabilities upon ageing at 700 °C, resulting in the degeneration of the γ-γ′ aggregate into i) a faulted Co-based martensite and CoTi and ii) a lamellar aggregate of A3-Co and CoTi. The faulted Co-based phase was formed by isothermal diffusionless transformation of the metastable A1-phase, whilst the lamellar aggregate was a discontinuous reaction product.
