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 ...
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 ...
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, ...
Chromium hardening and Peierls mechanism for basal slip in sapphire (α-Al2O3) at temperatures between 900 and 1500 °C
(European Ceramic Society, 2007)
The plastic deformation of Cr3+-doped α-Al2O3 (ruby) with four distinct Cr concentrations has been studied at temperatures between 900 and 1500 °C. The mechanical tests indicate that the processes of dislocation multiplication ...
Correlation between microstructure and creep behavior in liquid-phase-sintered α-Silicon Carbide
(The American Ceramic Society, 2006)
The influence of increasing the sintering time from 1 to 7 h on the microstructure evolution and the mechanical properties at high temperature was studied in α-silicon carbide (α-SiC) sintered in argon atmosphere with ...
Effect of atmosphere and sintering time on the microstructure and mechanical properties at high temperatures of alpha-SiC sintered with liquid phase Y2O3-Al2O3
(Elsevier, 2006)
The influence that the atmosphere (N2 or Ar) and sintering time have on microstructure evolution in liquid-phase-sintered α-SiC (LPS-α-SiC) and on its mechanical properties at high temperature was investigated. The ...
Effect of the heat treatment on the mechanical properties and microstructure of Scalmalloy® manufactured by Selective Laser Melting (SLM) under certified conditions
(Elsevier, 2023)
Mechanical properties and microstructure of Scalmalloy® processed by Selective Laser Melting (SLM) under certified conditions are studied. Two types of samples are considered: as-built and heat-treated at 325 °C for 4 h. ...
