| Abstract Scope |
Powder-based manufacturing processes such as Field Assisted Sintering Technology (FAST) have the potential to unlock a new era of multi-material or functionally-graded components for the aerospace industry. Currently, many are produced as monolithic single alloy structures and are over-engineered. As the drive towards net zero gathers pace, weight savings and subsequent emissions reductions due to more efficient component design are essential. This work demonstrates a method for engineering such components with site-specific properties via FAST, through diffusion bonding (FAST-DB) and functionally grading material (FGM). A number of titanium alloys and nickel-based superalloys have been successfully joined and functionally graded. Large-scale mechanical testing and extensive microstructural characterisation has been performed. Further assessments have been made of the bond’s response to downstream thermo-mechanical processing and machining operations. This technique offers designers a new dimension through which the next generation of high performance aerospace components may be produced. |
