Creep and microstructural evolution at high temperature of liquid-phase-sintered silicon carbide
(The American Ceramic Society, 2006)
The compressive creep characteristics at 1625°C of liquid-phase-sintered silicon carbide ceramics containing 5 and 15 wt% of crystalline Y3Al5O12 (YAG) as the secondary phase were studied. In the two cases, strains between ...
Dissociation of basal dislocations in 4H–SiC single crystals deformed around the transition temperature
(Wiley, 2013)
The dislocation microstructure was studied in 4H–SiC samples plastically deformed by basal slip activation around the transition temperature (1000°C–1100°C). Dissociation of basal dislocations takes place over a wide ...
Microestructura y propiedades mecánicas a altas temperaturas del α-SiC sinterizado con fase líquida de Y2O3-Al2O3
(Sociedad Española de Cerámica y Vidrio, 2005)
Muestras de α-SiC han sido sinterizadas con fase líquida (LPS) a 1950 ºC, en atmósfera de argón y tiempos de procesado
entre 1 y 7 horas. Mediante microscopia electrónica de barrido (SEM) se ha caracterizado la microestructura, ...
Influence of the processing route on the carbon nanotubes dispersion and creep resistance of 3YTZP/SWCNTs nanocomposites
(The American Ceramic Society, 2014)
3YTZP matrix composites containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250°C, following different processing routines with the aim of optimizing the SWCNTs ...
Origin of the low precipitation hardening in magnesium alloys
(Elsevier, 2019)
In this work electron backscattered diffraction (EBSD)-assisted slip trace analysis and transmission electron microscopy have been utilized to investigate the interaction of basal dislocations with precipitates in the Mg ...
High-temperature deformation mechanisms in monolithic 3YTZP and 3YTZP containing single-walled carbon nanotubes
(Wiley, 2015)
Monolithic 3YTZP and 3YTZP containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250°C. Microstructural characterization of the as-fabricated 3YTZP/SWCNTs composite ...
Comparative study on high temperature mechanical behavior in 3YTZP containing SWCNTs or MWCNTs
(Elsevier, 2016)
Effects on mechanical properties of the presence of either single-walled carbon nanotubes (SWCNTs) or multi-walled carbon nanotubes (MWCNTs) in a 3YTZP matrix have been investigated in this work. Thus, monolithic 3YTZP and ...
The kink-pair mechanism and low-temperature flow-stress behaviour of strontium titanate single crystals
(Elsevier, 2011)
The mechanical behaviour of strontium titanate exhibits a remarkable behaviour at low temperature, in the so-called regime A, where the flow stress experiences two different temperature dependences separated by a noticeably ...
High temperature internal friction in a Ti–46Al–1Mo–0.2Si intermetallic, comparison with creep behaviour
(Elsevier, 2016)
Advanced γ-TiAl based intermetallics Mo-bearing have been developed to obtain the fine-grained microstructure required for superplastic deformation to be used during further processing. In the present work we have studied ...
Creep study on alumina and alumina/SWCNT nanocomposites
(Elsevier, 2018)
Alumina and alumina/SWCNT nanocomposites have been sintered by spark plasma sintering, obtaining relative densities higher than 99%. Microstuctural characterization revealed a grain microstructure in the submicron range, ...
