A novel process for the large-scale synthesis of nanostructures is proposed and demonstrated using alloys in the Ni-Co-Al system. The synthesis technique involves developing nanoscale two-phase microstructures through discontinuous precipitation followed by selective etching to selectively remove one of the phases. The technique has been demonstrated using the discontinuous precipitation of a γ′ phase (Ni, Co)3Al, followed by selective dissolution of the γ matrix phase. Through control of the composition and aging parameters it is possible to produce plates of different thickness and different spacings. The method is easily scaled up and may be generally applied to any alloy system undergoing a complete discontinuous precipitation transformation This synthesis technique opens up new areas of potential applications through selection of the plate composition and additional functionalization.
