"Presented work deals with properties of compacts sintered via Spark Plasma Sintering (SPS) - novel non-conventional poder consolidation technique. The sintering parameters were set to be 450\u00B0C as the temperature for the application of the pressure and 1000 and 1100\u00B0C as the sintering temperatures. The loose sintered material was a gas-atomized Fe-Al intermetallic >32 um powder. The sintered samples were machined in shapes of round compact tension specimens. The central notches were obtained by electrical discharge cutting. The increase of the sintering temperature resulted in slight increase of fracture toughness. The study of the fractured surfaces revealed similar fracture mechanisms - interparticle decohesion. Only very few areas of transparticle cracks were observed in case of 1000\u00B0C as well as 1100\u00B0C specimens." . "Fracture Toughness of Spark Plasma Sintered Fe-Al Based Intermetallics"@en .
