| Abstract Scope |
A common approach to achieve dual-property of components that fully meet service conditions is dual-microstructure fabrication, which is, however, often done through complex processes, e.g., joining of dissimilar parts or dual microstructure heat treatment. The plasticity induced dynamic precipitation provides a new approach to achieve dual-property by tailoring the volume fraction and average size of the second-phase particles. In this study, the compression of nickel-based superalloy is divided into several steps, during which the deformation temperature, strain and strain rate are tuned to obtain a matrix with desirable properties. Meanwhile, the nucleation and growth of the second-phase particles are controlled with the help of an additional magnetic field mounted at localized area of the component. The magnetic field is enabled only when it promotes precipitation. Preliminary results suggest that the fabricated components can indeed achieve dual-property under a single matrix where areas with more and finer particles exhibit better properties. |
