TL;DR: In this article, a systematic study of various spark plasma sintering (SPS) parameters, namely temperature, holding time, heating rate, pressure, and pulse sequence, was conducted to investigate their effect on the densification, grain-growth kinetics, hardness, and fracture toughness of a commercially available submicrometer-sized Al 2 O 3 powder.

TL;DR: In this article, the authors show that the pre-existing dislocation network, which maintains its configuration during the entire plastic deformation, is an ideal modulator that is able to slow down but not entirely block the dislocation motion.

TL;DR: In this paper, a feasibility study was performed to fabricate ITER In-Vessel components by Selective Laser Melting (SLM) supported by Fusion for Energy (F4E), almost fully dense 316L stainless steel (SS316L) components were prepared from gas-atomized powder and with optimized SLM processing parameters.

TL;DR: The very fast (within minutes) in situ formation of a tough interlocking microstructure in Si3N4-based ceramics is reported, which is uniform and reproducible in terms of grain size distribution and mechanical properties, and are easily tailored by manipulating the kinetics.

TL;DR: Spark plasma sintering (SPS) is a comparatively new technique as mentioned in this paper, which allows very fast heating and cooling rates, very short holding times, and the possibility to obtain fully dense samples at comparatively low sinterings temperatures, typically a few hundred degrees lower than in normal hot pressing.
