The discontinuous precipitation of γ’ phase in Ni-Co-Al alloys can go to completion in certain Ni-Co-Al alloys through control of the precipitation process parameters. The discontinuous transformation product consisting of γ/γ’ alternating lamellae can be produced on a scale of less than 100nm. Through appropriate electrolytic etching it is possible to selectively remove the γ phase lamellae leaving a structure of γ’ lamellae spaced about 50nm apart. The physical and mechanical properties of the microstructure have been studied.
