Aims of the project: Field assisted sintering technique (FAST) also known as SPS or PECS is routinely used for compaction of metallic or ceramic powders. This pioneering project aims on exploring alternative - non-conventional - applications of FAST. Firstly, processing by FAST can be used as an in-situ annealing treatment to achieve optimal phase composition and, ultimately, favourable mechanical properties. This option will be investigated for aerospace high strength lightweight Ti-based alloy Ti5553. Secondly, enhanced diffusion during FAST allows alloying of complicated alloys from elemental powders. Specialized biomedical Ti-Nb-Zr-O alloy will be prepared by high-temperature sintering. Thirdly, composites prepared by sintering of bulk materials (wires or 3D printed structures) with powder of another material will be manufactured: in particular lightweight Al/Ti composite and high-temperature TiAl/ceramic composite. Advanced experimental techniques will be employed for detailed characterization of manufactured materials.
