SiC-ZrO2(3Y)-Al2O3 nanocomposites superfast densified by spark plasma sintering

Spark plasma sintering (SPS) - an advanced sintering technique for structural nanocomposite materials

“…A moderate increase in fracture toughness 3.6 MPa.m 0.5 and flexural strength of 812 MPa was obtained for Al 2 O 3 -20 vol% SiC, lower than obtained by Niihara et al (1989). Similar microstructural observations were claimed by Gao et al (1999a) for Al 2 O 3 -5 vol% SiC densified at 1500°C for 3 minutes. A fracture toughness value of 4 MPa.m 0.5 was obtained, and the microstructures revealed that the SiC particles were located mainly inside the Al 2 O 3 grains with the fracture mode being mainly transgranular.…”

“…The majority of the work has been done on the Al 2 O 3 /SiC system (Golla and Basu, 2014;Yamamoto et al, 2008;Chae et al, 2006;Choa et al, 1998;Gao et al, 1999aGao et al, , 1999b. Since the pioneering work of Niihara (1991) (Golla and Basu, 2014;Yamamoto et al, 2008;He et al, 2009;Wang and Steven, 1989;Nieto, Lahiri, and Agarwal, 2012;Liu et al, 2012;Chae et al, 2006;Choa et al, 1998;Gao et al, 1999aGao et al, , 1999bTaya et al, 1990).…”

One of the motivations for interest in SiC-reinforced composites is the toughening mechanism associated with the composites, referred to as residual stress toughening.…”

Tin Oxide Based Composites Derived Using Electrostatic Spray Deposition Technique as Anodes for Li-Ion Batteries

“…This matrix can also prevent the aggregation of tin particles. Composites can improve conductivity, relieve stress, and improve electrochemical performance [86][87][88][89][90][91]. For example, in SnO 2 /C composites, the conductivity is enhanced by carbon [86].…”
