“…Deng et al [107], Chen et al [108], and Sim et al [109] all utilised ball milling of a variety of alloys to achieve UFG microstructures to ascertain effects on mechanical properties. Lu et al [110], Liu et al [111], Karakozov et al [112] and Martins et al [113] all investigated optimisation of FAST parameters to improve microstructures and mechanical properties in Ti-45Al-8.5Nb-0.2W-0.2B-0.1Y, Ti-48Al, Ti-23.5Al-21Nb and Ti-48Al-2Cr-2Nb alloys, respectively. FAST of TiAl powders has been a research focus of the Centre d'Élaboration de Matériaux et d'Etudes Structurales (CEMES) in Toulouse [114][115][116][117][118][119][120][121][122] leading to the development of the Ti-48Al-2W-0.08B IRIS alloy with reportedly excellent mechanical properties [123,124], and single-step FAST consolidation to nearnet shape of a γ -TiAl turbine blade with excellent properties [125].…”

The current status of field assisted sintering technology (FAST) of structural metals from powder is critically reviewed. Recently, there have been significant increases in the uptake of FAST for metallic systems, composites and porous materials at the laboratory-scale. It is clear that FAST is tolerant of powder/particulate feedstock, allowing rapid production of materials, some of which would be challenging through conventional sintering techniques. Yet, the underlying mechanisms allowing this are not fully understood. Final specimen sizes tend to be small, which restricts rigorous mechanical assessment. This review demonstrates the clear benefits in transitioning laboratory-scale demonstrators to the industrial scale over the next few years. However, consideration will need to be given to size, throughput, and shape complexities to attract commercial investment.
