“…[226,242] Graphite, which is used in most cases in literature (typical specific electric resistivity 15 mV m, compressive strength 100-150 MPa) can be reinforced with carbon fibers to increase its mechanical strength. [43] For sintering temperatures below 1000°C, steel and refractory metals such as TZM molybdenum alloys, copper-beryllium, alumina, [243] silica, [244] and even concrete [245] were used. Anselmi-Tamburini et al [141] used binder-free tungsten carbide parts with silicon carbide inserts.…”

Field-assisted sintering technology/Spark plasma sintering is a low voltage, direct current (DC) pulsed current activated, pressure-assisted sintering, and synthesis technique, which has been widely applied for materials processing in the recent years. After a description of its working principles and historical background, mechanical, thermal, electrical effects in FAST/SPS are presented along with the role of atmosphere. A selection of successful materials development including refractory materials, nanocrystalline functional ceramics, graded, and non-equilibrium materials is then discussed. Finally, technological aspects (advanced tool concepts, temperature measurement, finite element simulations) are covered.
